The referee for Arsenal 's Champions League semi-final second leg against Paris Saint-Germain has been confirmed and it is a somewhat controversial appointment.
Felix Zwayer will be the man in the middle at the Parc des Princes as Arsenal look to overturn a 1-0 deficit from the first leg at the Emirates Stadium last week.
Ousmane Dembele scored the only goal of the game in north London to put PSG in the driving seat against Mikel Arteta 's side.
Zwayer hit the headlines in 2014 when it was revealed he had been part of a match-fixing scandal in Germany in 2006. Working alongside referee Robert Hoyzer, Zwayer claimed he was asked to fix a match between Rot-Weiss Essen and Cologne in the 2. Bundesliga.
There was also a 2. Bundesliga game involving Wuppertal and Werder Bremen B in which the German football federation (DFB) found that Zwayer had accepted a €300 payment from Hoyzer.
Zwayer was given a six-month ban for his part in the scandal, but always maintained his innocence, saying: "When I got this firm offer from Hoyzer, I went to my refereeing colleagues. I stress once again that I strongly rejected this offer straightaway."
Zwayer was in the headlines once more in 2021 when England star Jude Bellingham called him out for his history after his then team Borussia Dortmund had lost 3-2 to Bayern Munich in a tempestuous affair in the title race.
Bellingham had said: "You give a referee that has match-fixed before the biggest game in Germany - what do you expect?
"For me, it wasn't [a penalty]. He [Hummels] is not even looking at the ball and he's fighting to get it and it hits him. You can look at a lot of the decisions in the game."
UEFA gave their full backing to Zwayer, however, with the governing body having no concerns over his suitability to oversee top-level matches in its competitions, as shown by his appointment for the huge semi-final second leg clash on Wednesday night.
This will be Zwayer's 15th Champions League clash since those comments by Bellingham and will be his seventh Champions League match this season.
