Arsenal goalkeeper Petr Cech says it will be an emotional affair if his side meets Chelsea in the Europa League final this season.

Both teams are on the verge of qualification ahead of Thursday night's second leg semifinal fixtures and might set up an all-English affair in the finals. 

Chelsea host Eintracht Frankfurt at Stamford Bridge with an away goal after the 1-1 draw away to Frankfurt, while Arsenal take a 3-1 lead to Spain to face Valencia. 

"Playing against Chelsea in the final looks a big possibility, with us in a good position and them having the second game at home," Cech told The Daily Mail. 

"You have the last game of your career, a European final and then you have an emotional attachment to the opposition team, which probably is a bit too much. But if it happens, it happens," he added.

Cech announced that he will be retiring from professional football at the end of the current campaign, with the Europa League final his possible last match, subject to qualification.  

The Czech international played for Chelsea in his best years, in which he won numerous titles including the Champions League, Europa League and English Premier League titles.
