Olly: In 2016, Klopp put all his eggs in the Europa League basket and failed to win it. In 2017, Mourinho did the same thing and won. I'm looking forward to seeing Wenger having a crack this season.

Antony: Arsenal have proved to be flaky on most of the big occasions. If the defence play up to their usual standard then CSKA might be in for a useful away win.

Arsenal v CSKA Moscow (20:05 BST)
Image source, .Arsenal are the top scoring side in the Europa League this season - with 23 goals in 10 games.

The top scoring player is Athletic Bilbao's Aritz Aduriz on nine.
Arsenal's top two scorers - Theo Walcott and Olivier Giroud (three goals each) - left the club in January.

Arsenal v CSKA Moscow (20:05 BST)
BBC Radio 5 liveFormer Arsenal defender Lauren says any talk of Arsene Wenger's future can wait until the summer.
“Obviously we all want Arsenal to be fighting to win the league, to qualify for the Champions League next year," he told BBC Radio 5 live.
"But the most relevant thing today is to win the game. Win the game, qualify for the next round, and try to win the Europa League.
"After the season ends, then we can talk about who’s going to be sacked or not.
“The most important thing is the institution. We all come, we all go. Arsene is there, Arsene will go - but what will remain is the institution. Arsenal will be there forever."
