Bukayo Saka's quick equaliser saw Arsenal grab an important away goal in a 1-1 draw against Benfica in their Europa League last-32 tie in Rome
It has been a cagey first half at the Stadio Olimpico and Arsenal should have gone into the break in front, but Pierre-Emerick Aubameyang fired just wide with only goalkeeper Helton Aleixo Leite to beat
But the game livened up after the break and Benfica were awarded an early penalty when Emile Smith Rowe was penalised for handball
 Europa League top scorer and captain Pizzi (55) dispatched from the spot
However, their lead only lasted a few minutes as Arsenal hit back almost instantly
 Cedric Soares, who started his career at Benfica's fierce rivals Sporting Lisbon, fired in a cross that was turned home by Saka
 VAR checked the goal for offside - Arsenal were flagged 10 times during the game - but it stood
The last-32 tie is finely poised for the second leg next Thursday in Athens with Arsenal holding a slender advantage with the away goal
Arsenal began well in Rome and should have taken the lead inside 20 minutes
 Hector Bellerin sent a fizzing cross in from the right, which met an open Aubameyang at the far post
 However, the striker could only place his effort wide of the post from close range in an agonising miss
Arsenal had another sight of goal shortly after, but after a driving run along the top of the area from Saka, his effort curled harmlessly into Helton Leite's hands
 Bernd Leno almost fluffed his only save of the half as Darwin Nunez fired straight at him, spilling the shot before pouncing on the loose ball
Benfica had one of their chances of the half in injury time
 Alex Grimaldo nipped through to take advantage of a wayward Granit Xhaka pass, but his attempted cross pinged off the head of Soares before going behind for a corner
The second half was a much livelier affair and eight minutes in, Benfica were awarded a penalty
 Diogo Goncalves' attempted cross from a short corner hit Smith Rowe on the chest and onto his raised arm, with the referee pointing to the spot
 Benfica captain Pizzi then slotted home past Leno to hand the designated hosts the lead
But it lasted all of two and a half minutes
 A superb Martin Odegaard pass picked out Cedric down the left of the area, with his zipped cross turned home by Saka from close range
 VAR checked for offside but it was allowed to stand as Arsenal nabbed the all-important away goal
Both sides went close soon after as the half continued apace
 Leno made a fine, leaping save to keep out half-time substitute Rafa Silva
 But it was not Aubameyang's night at the other end as he sent another effort wide, this time past the far post, taking a small nick off the woodwork on the way through
There were some half chances as the game continued but neither side could take them and had to settled for a first-leg draw
It was an impressive performance from the Real Madrid loanee on only his second Arsenal start
 He made some superb passes throughout and flourished in midfield - and it was Odegaard's brilliant ball to pick out Cedric on the left that led to the goal
The only downside was that more of his passes did not manifest into goals
 If it has only taken a handful of games for Odegaard to be this good for Arsenal, it bodes well for the future
Arsenal boss  told : "My feeling is that we should have got more from the game from the amount of chances that we created and the dominance that we showed in the game
"We should be in a much better position than we are, we haven't been ruthless enough in the opponent's box and then we gave them a goal with the actions leading to the corner and then the handball
 Everything is still to play for on Thursday
"I think it [the penalty] is harsh
 He touches the ball maybe on his body before it touches his hand
 I'm more upset about what led to the corner in an area we should not be playing than the penalty
"To be fair, the reaction from the boys was brave, we continued, we didn't lose the focus, we went for the goal and to win the game
 We scored a goal and I think we should have scored two or three more
"I am positive [for the second leg]
 It's really difficult to see what the 'home' game is going to be like
 We're going to be playing in Greece with no crowd and everything will be a bit strange but we're going to go there to win the game
"Benfica head coach  added: "Our ambitions remain
 The tie is open, it is true that the away goal can have an influence in the end
 It's another game away in Greece that we're going to try to win
 We played against a team that has a lot of quality and great players
"Arsenal are back on on Sunday as they host Premier League leaders Manchester City; kick-off 4
30pm
 Benfica face Farense in the Primeira Liga, also on Sunday
The pair will then travel to the Karaiskakis Stadium in Greece - home of Olympiakos, who knocked Arsenal out of the Europa League last season - for the return leg next Thursday
