Arsenal have secured a crucial 2-1 win over champions Liverpool at the Emirates to keep their European hopes alive.
Sadio Mane put the visitors ahead after 20 minutes on Wednesday night when he converted Andy Robertson's cross with a clinical close range finish.
12 minutes later and Arsenal would have their equaliser thanks to an uncharacteristic mistake from Virgil van Dijk.
The Dutchman's shocking back-pass was cut-off by Alexandre Lacazette, who rounded Alisson and finished calmly. Van Dijk felt he was fouled by Reiss Nelson before giving possession away but the goal stood.
Then it was Alisson's turn to gift a goal to the hosts. The Brazilian attempted a cute chip to Andy Robertson on the left-flank, only for Lacazette to intercept and set-up Reiss Nelson to put Arsenal ahead at the interval.
The defeat means Liverpool will not reach the 100-point mark this season with two games remaining.
For Mikel Arteta, the result was huge in terms of Arsenal's European hopes. The Gunners are now within two points of seventh-placed Tottenham, who also won on Wednesday.
Both North London sides will be hoping Sheffield United is unable to climb into seventh with a win over Leicester tomorrow.
Speaking after the game, match-winner Reiss Nelson said: "It's a big achievement for us. We've been working hard in training. Getting a win against the leaders is a great result.
"You dream as a little boy to score against the big boys, so I'm happy with the goal and the result. When I get home I'll celebrate with my family, I'm really delighted. The boss said keep pressing, and I think we did very well, we were eager to keep pressing them."
