Rennes forward Hatem Ben Arfa mocked Arsenal manager Unai Emery after his side beat the Gunners 3-1 on Thursday in the UEFA Europa League.
Ben Arfa fell out of favour at Paris Saint-Germain when he played there under Emery, and he was quick to aim a dig at the Spaniard following Rennes' win in the first leg of their last-16 tie.
Per Metro, he said: "My motivation was to play a solid match, to win and get ourselves into a good position to go through. That's what was in my head. But I did see the same Emery, as agitated as ever. I looked over at him a few times, and that made me laugh a little. He hasn't changed."
Ben Arfa signed for PSG in 2016, just three days after Emery was appointed manager. The Frenchman made 32 appearances under him in his first season but started just 10 times.
He was dropped from the side in April 2017 and did not play again until he left the club last summer, having spent the entire 2017-18 campaign with the reserves.
It was clear he had a point to prove on Thursday, his 32nd birthday:
Arsenal started strongly at Roazhon Park, taking an early lead through Alex Iwobi when his cross sneaked in at the back post.
The game took a turn for the worse for the Gunners shortly before half-time, however. Sokratis Papastathopoulos, who had already been booked for a challenge on Ben Arfa, felled Ismaila Sarr during a Rennes counter-attack and was sent off.
Rennes immediately compounded his exit thanks to Benjamin Bourigeaud:
In the second half, the French side took the lead when Mehdi Zeffane's cross deflected in off Nacho Monreal, and Sarr added a third late on:
Rennes will thus take a two-goal lead with them to the Emirates Stadium for Thursday's second leg, and Ben Arfa is confident they can complete the job:
In the Premier League, only five points separate Tottenham Hotspur in third and Chelsea in sixth. The Gunners are fifth, one point ahead of Chelsea and one behind Manchester United.
The race for UEFA Champions League qualification will go down to the wire, and there's a good chance Arsenal might be one of the two who miss out.
The Europa League is their alternative and the only silverware they can win this season, so it's vital they continue to progress.
Having an away goal will help, but they will need to be at their best to overturn this deficit against an impressive Rennes side.
