Arsenal boss Arsene Wenger says Lukasz Fabianski will start their FA Cup semi with Wigan Athletic.
Fabianski has been the Gunners' Cup keeper this season ahead of Wojciech Szczesny.
"You play football on your merit and your performance and he has turned up with top-level performances until now in every single game," Wenger said.
"When you are a professional you work until the last day of your contract. That is for me being professional.
"All the rest has nothing to do with professionalism."
