Future team-mates at Manchester United?
De Gea made 14 saves at the Emirates Stadium - matching the most in a Premier League game - to ensure United left North London with a vital victory in the title race.
It was a pulsating contest from start to finish at Emirates Stadium, with a glut of shots on goal, awesome goalkeeping, a sending off, and textbook counter-attacks.
"You know - if you are my friends, don't ask me the question, because you know I get into problems". "If I was in the stands, or if I was at home watching, I would be sad to see the game finish". We have lost games here against Man United where we didn't deserve anything.
Paul Pogba might also have been, until ruining his performance... United clinically finished again, with Anthony Martial's incredibly deft flick meeting Lingard's impressive side-footed finish inside the far post. Midfielder Aaron Ramsey was onside when he touched the ball back to Lacazette who fired it past De Gea.
What Guardiola told Redmond after City's dramatic win over Southampton
Guardiola approached Redmond moments after Raheem Sterling had scored a 96th-minute victor for the league leaders at Etihad Stadium.
Most remarkable of all was a double De Gea save to deny Alexandre Lacazette and Alexis Sanchez with the score at 2-1 early in the second half. "I just know that Paul is frustrated and a bit disappointed with his [France] colleague [Laurent Koscielny] for his reaction, because everyone knows Paul is a clean player and it was not his intention". But when United are playing on the break, countering with speed, a player like Lingard is ideal.
But the smiles turned to frowns when Pogba went studs up into Bellerin's ankle, an easy red card and a huge obstacle for Jose Mourinho in the Manchester Derby.
Wenger's side fired 33 shots at goal, with 15 finding the target.
It was a statistic that upset Wenger, who lamented missed chances. I think in the end, it was an expression.
It was Mourinho's first away victory in 11 games against the "Big Six" and the first home loss for the Gunners after winning their last 12.
