#1 Simon Mignolet (Belgium)
The Liverpool shot-stopper is usually the second choice goalkeeper for Belgium, behind Thibaut Courtois from Chelsea. In January this season, Klopp dropped Mignolet in favour of Loris Karius.
Both keepers have had a fair share of low-quality performances, but now it seems like Mignolet has lost the trust of Klopp to continue playing on. However, there is still a high chance for Mignolet to be in the World Cup even though he may be the backup keeper.
Courtois' injury and fitness concerns mean that there is a chance for Mignolet to stand in whenever it is demanded of him. However, it is unlikely that the latter will replace Courtois when he is fit given that the Chelsea keeper is more highly rated.
