Manchester City beat Aston Villa 3-1 to move within three points of Arsenal but Erling Haaland had to be taken off with an apparent injury ahead of Wednesday's showdown at the Emirates Stadium
After a turbulent week in which , Pep Guardiola's side roared into a three-goal first-half lead through Rodri (4), Ilkay Gundogan (39) and a Riyad Mahrez penalty (45+1)
But Haaland, scorer of 25 Premier League goals this season and creator of City's second, had to be , becoming a doubt for Wednesday's trip to Arsenal, with Ollie Watkins then pulling a goal back for Villa (61)
That goal ensured Unai Emery's side avoided a heavy defeat, the visitors improving after half-time having been totally dominated in the first period, but the damage was already done at that point, ensuring City capitalised on Arsenal's failure to beat Brentford
Guardiola's side now head to the Emirates Stadium knowing victory would put them top of the Premier League table on goal difference, but whether they can call on Haaland remains to be seen
"He had a big knock, he wasn't comfortable," Guardiola told  afterwards
 "We didn't want to take a risk
 We'll see
 We'll assess in the next days
"Guardiola had struck a defiant tone on the charges levelled at City in the lead-up to the game, with supporters loudly booing the Premier League anthem before kick-off, and there was a clear determination to prove a point on the pitch as well as off it
Rodri celebrated his opening goal, powered in at the near post from Mahrez's corner, by thumping the badge on his chest and the Spaniard almost set up a second shortly afterwards, his pass releasing Gundogan, whose effort was well saved
City continued to pin Villa back, with Calum Chambers subjected to a bruising first 45 minutes on his first Premier League start since August, and the hosts created a succession of other chances, Jack Grealish twice going close before Gundogan scored the second
Haaland came into the game having failed to register a shot against Tottenham but he caused Villa problems and was the architect of the second, accelerating onto a loose ball after a poor Chambers header, then picking out Gundogan at the far post
City were rampant at that point and the third goal came when Grealish, eager to impress against his former side, won a penalty off Jacob Ramsey, and, following some discussion about who would take it, Mahrez stepped up to beat Martinez
By that point, Haaland appeared to have picked up a thigh problem and he did not emerge for the second period, with Ruben Dias also withdrawn as Julian Alvarez and Manuel Akanji joined the fray
It appeared City were picking up where they left off when Rodri saw a low effort well saved by Emiliano Martinez, but defensive sloppiness crept into their performance after that as Emery's substitutions inspired some improvement from the visitors
The goal came when Bernardo Silva, deployed in an unusual midfield-cum-left-back role, was robbed of possession in his own half, allowing Douglas Luiz to release Watkins, who finished coolly
Ezri Konsa made a goalline block from Julian Alvarez and Mahrez scooped another glorious chance over the bar, but Villa continued to look dangerous at the other end, with Jhon Duran crashing a shot against Ederson's bar and Philippe Coutinho, another substitute, also threatening
That defensive shakiness ensured this was not quite the City statement of intent it looked like it might be at half-time
 Haaland's injury is a worry too
 But the victory was much needed after the 1-0 loss to Tottenham and gives the defending champions the opportunity to go back to the top of the pile on Wednesday
Man City boss  told : "We played a really good game
 We played better in the second half
 I had the feeling we were going to score more but after we concede always at 3-1 in the Premier League it's open, but in general we played a good game
"On Erling Haaland's injury scare, he added: He had a big knock, he was comfortable and we didn't want to take a risk
 We will see and assess in the next days
"If he's not ready [for Arsenal], we'll play another one
 Hopefully he is ready like everyone - we will see in the next days
""His presence is really good, he just has to take a look a little bit more when we have pressure on the ball
 When the opponent has a high line, we need to find him a bit more
 That's a process, we will do it in the future
"On reducing the gap to Arsenal, he said: "Finally when they drop we were there to reduce the distance as in the past when we could have put pressure on them we fail
 When they dropped points, we fail - finally today we could do it
"Aston Villa boss  told : "We were very competitive away [in our previous games] but today we knew before that it was a tough match and it was like that
"The first half, we weren't competitive
 They were also clinical but the mistakes were ours today
 Three goals we could normally avoid in other matches
"In the second half we tried to be consistent on the pitch, tried to forget the result and to be again competitive and I think we did that
"But in the first half they were better than us
 They decided the match without mistakes
"I can only say sorry to the supporters but we continue in our way
 Our next match is our challenge, against Arsenal at home
 We want to show our supporters a good performance
"Erling Haaland tends to dominate the headlines with Manchester City and that is sure to continue following his early withdrawal on Sunday
 But this was just another game to show why Rodri might be even more important to the team
Pep Guardiola's starting line-up had many wondering whether the Spaniard might be drafted into defence before kick-off but in truth he is too influential for that
 City need him in the heart of it all and that's where he was, once again, controlling the game
The numbers reflected his dominance, the 26-year-old ranking top among all players for touches, passes, chances created and duels
 His goal, headed in from Riyad Mahrez's early corner, set the tone for City's rampant first-half performance
It was also his ninth in the Premier League since the start of last season, a period during which he has also registered a total of six assists
 They are figures which show that he is much more than a holding midfielder for Guardiola and his team
Arsenal know that well
 It was Rodri, of course, who scored City's stoppage-time winner in their last visit to the Emirates Stadium
 "We need to show we are better than them," he said of Wednesday's game in his post-match interview with 
If Rodri produces another performance like this, then, Haaland or no Haaland, City might well do it
