Fulham boss Martin Jol was furious with the manner of their 1-0 Europa League defeat at Wisla Krakow.
Mousa Dembele's controversial sending off paved the way for the Polish champions to secure their first Group K points, with David Biton striking the all-important goal in a 1-0 win at Stadion Miejski.
The incident occurred when an innocuous passage of play flared up, with Dembele pushing over Gervasio Nunez after he caught him on the back of the ankle.
The Argentinian midfielder went down clutching his face despite being pushed at shoulder height, leading referee Martin Hansson to hand the Belgium international a straight red card.
"You could say it was a frustrating evening," Jol said after the match. "Before the sending off I think we were in control.
"The pace was good, possession play was good and I was very satisfied.
"Then we got a straight red card and that makes it difficult for any team.
"After that they had more confidence, of course, because they played with 11 players and it was an awful night for us.
"Even after that we should have had a couple of decisions. You can't say anything about the referee, bad or good."
