Kieran Tierney's sublime first-half strike was enough to ensure Arsenal held onto top spot in Europa League Group A as FC Zurich were beaten 1-0 on a nervy night at the Emirates Stadium
Tierney kept his composure to spear a finish from the edge of the box shortly after the quarter-hour mark, but it wouldn't open the floodgates for Mikel Arteta's side, who finish their group-stage campaign with just eight goals from their six games
Zurich came close to equalising when Adrian Guerrero's finish was ruled out for offside but the result means the Gunners are now unbeaten in 14 home matches in all competitions, with PSV now facing a play-off against a third-place finisher in the Champions League
Zurich's failure to better Bodo/Glimt's result means it is the Norwegians who finish third in Group A, qualifying for the Europa Conference League knockout-round play-off, where they will face a group runner-up from that competition
Attention now turns to domestic action for Arteta, with Arsenal looking to consolidate their position at the Premier League summit when they visit Chelsea on Sunday, but they are set to be without Takehiro Tomiyasu after the full-back was forced off with an injury in the closing stages
"We always try to start faster but there's always the opponents who look to make it as hard as possible," the Gunners boss said
 "We knew it was going to be tough
 We struggled to get momentum and we have to adapt as we didn't control certain situations and we have to dig in
 We found a way to win
"Losing football matches is part of it, as it happens, but it's how you react to that, analyse what happened and come back stronger as a team
 We've done that in the last two games and now it's onto Stamford Bridge
"The Gunners knew they would top Group A if they matched PSV Eindhoven's result away to Bodo/Glimt - or if the Dutch club failed to win - but they took the lead against the run of play on 17 minutes
Reiss Nelson, fresh from his double in the 5-0 win over Nottingham Forest, combined with Ben White down the right before Fabio Vieira's blocked shot landed kindly for Tierney to direct a precise shot low into the bottom corner
It was the Scotland full-back's first goal of the season, and Arsenal came close to doubling their advantage five minutes later when Vieira set up Eddie Nketiah for a 25-yard drive that was parried to safety by Yanick Brecher
Zurich arrived in North London in poor form; their comeback victory on Matchday 5 against Bodo/Glimt ended a run of 13 games without a win across all competitions, but they followed up that success with another defeat last Sunday against Sion
The visitors threatened sporadically in the opening period, with Jonathan Okita's deflected shot drawing a smart save from Aaron Ramsdale before Fidan Aliti's header from a set-piece failed to trouble the Arsenal goalkeeper
The Swiss club, who had only won one of their previous 17 away games in major European competitions - never beating an English club on their travels - ought to have fallen further behind when Vieira latched onto Nketiah's clever pull-back but his shot was blocked by Gabriel Jesus, standing in an offside position
Vieira was always involved, having another tame shot blocked by Guerrero before the interval, and moments after the restart it was Jesus who would be denied by Brecher's starfish save from point-blank range
 It is now eight games without a goal for the Brazilian
"It's going to change," Arteta vowed afterwards
 "He's getting the chances, he's contributing to the team an awful lot
 The way he competes is incredible
"He needs to be patient as it's happened in the past
 He needs to learn from those lessons and not stop doing the things that are helping the team
 That will maintain the level of him and the team
"PSV were doubling their lead in Norway, meaning anxious faces in the stands, and those concerns were almost realised when Guerrero found the net after Ramsdale had kept out Antonio Marchesano's first-shot back across goal
The offside flag came to the rescue of Arsenal, who had summoned Bukayo Saka from the bench in search of the killer insurance goal
 Martin Odegaard and Thomas Partey were also introduced
 Arteta wanted the comfort of a second, but this turned into a disjointed second-half display
With PSV home and hosed against Bodo/Glimt, Zurich manager Bo Henriksen sensed a famous point which would have meant his side snatching the Europa Conference League play-off berth
He summoned Bogdan V'Yunnik from the bench and it was his crisp shot which arrowed just wide of Ramsdale's post inside the final 10 minutes
Arsenal held on for the victory, meaning they will head straight to the last 16 after Christmas, but it would come at a cost
 Tomiyasu was a late introduction, but would be replaced before the final whistle with a hamstring injury which could severely impact his chances of going to the World Cup with Japan
"We don't know [the full extent of the injury]," said Arteta
 "He felt something and we didn't want to take a risk
 Unfortunately it happened to Tomi today but the rest have to be ready as we're going to need everyone
 We don't know yet
"Tierney's winner keeps Arsenal rolling, for now
 And onto Chelsea and Aubamayeng on Sunday
"It's job done
 It is not easy to win that many games in Europe
 I don't think it was the prettiest game we have played but we manage to win it
"I think we had chances, especially early in the game and at the end of the first half to get it into a more comfortable position
 We didn't do that
 We did not control the game well enough, especially in the second half
 At the end we were a bit leggy I think
 We gave them one or two chances but managed not to concede and keep a clean sheet and win
"We have been rotating
 I think we are the team that have been rotating the most in Europe today
 Players deserve chances and minutes and also the amount of games we play means we cannot maintain the intensity and players being fit
"We have all the games and fixtures in our minds to try and be competitive all the time
 Today was really important
 We know how important it is going to be with all the teams playing in February
 Winning helps winning
 The atmosphere in the dressing room is much better after a win than a loss
"It does bother him for sure [Gabriel Jesus not scoring for eight games]
 When he scores two he wants to score four
 Today he had a couple of good chances
 But what he generates for the team is amazing
 Last week he gave three assists
 Today he was involved in every action again
 The goals will come
""Takehiro Tomiyasu pulled his shirt up over his head in frustration
 The Japanese full-back had been a late substitute in this tetchy affair but he would not last long on the pitch, replaced by Cedric Soares due to a muscle injury which adds to the growing concerns now facing Arteta
"Arsenal are top of the Premier League pile, they clung onto top spot in the Europa League, but his squad is now being stretched
 For much of this opening chunk of the season the Spaniard has had a starting XI you could almost read out from memory, but having made seven alterations ahead of a crucial London derby on Sunday, he is left again picking up the walking wounded for Chelsea
"The return of Saka for a second-half cameo was as welcome as it was necessary, given how Arsenal toiled and failed to put an obdurate but limited Zurich to bed
 Tierney's goal was a thing of beauty and worthy of winning any match and it is the avoidance of two additional games in a play-off that will delight Arteta the most
"Fabio Vieira impressed in the opening period, and arguably should have added to Arsenal's lead, with his three shots yielding a game-leading xG of 0
