Thibaut Courtois proved just how vital a goalkeeper can be to a club in Europe – and Mignolet will want to show he can be just as good as his compatriot.
The Belgian’s form has improved of late but there is no getting away from the fact that he can make errors that cost goals.
Against the Turkish side, Mignolet will need to be error free and have no lapses in concentration – or his side will be punished for them.
