Arsenal goalkeeper Petr Cech admits potentially facing Chelsea in the final game of his playing career would be "too much".
The 36-year-old will retire at the end of this season after starring for both the Gunners and Chelsea in his illustrious career.
Both London clubs are one game away from reaching the Europa League final, and Cech says that should both teams qualify, the occasion would be tough for him considering his history with the Blues.
"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. "I don't know if it's a dream scenario.
"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."
