Andre Onana
The Cameroon international has been linked with a move to Stamford Bridge in the last couple of days.
If we look into the stats, Onana would be a suitable choice, with a save percentage of 76.4% which is up there with the best in the top five European leagues this season.
When we compare his post-shot xG conceded with the actual number of goals he has let in, though, his score is -1.8, which means he may not be the best option.
