#4 Andre Onana (Ajax)
Chelsea's goalkeeping situation is definitely a cause of concern, as Kepa Arrizabalaga has been dismal between the sticks for them this season. The Spanish goalkeeper was signed for a world record fee last summer but has failed to perform consistently in the premier league, leading to rumours that Chelsea are eyeing up replacements for him.
In Andre Onana, the Blues could have the perfect replacement for the Spaniard, as the Cameroonian has been rock solid for Ajax. In the Champions League this season, Onana featured against the Blues and impressed, as he made a string of stunning saves despite Ajax's elimination from the competition.
At the age of 23, his best years are ahead of him and he seems like a more reliable presence at the back than Arrizabalaga, who has struggled since making the move to England. Onana has never hidden his admiration of playing in the Premier League, saying in November that he'd be more than happy for his next move to be to a club in England and is expected to cost around £50 million.
With Chelsea losing patience with Arrizabalaga and reportedly looking to cut their losses and let him go this summer, they should look no further than Onana to replace the Spaniard between the sticks.
