3 Keepers Chelsea could target to replace Thibaut Courtois 

#2 Jack Butland

Butland would be available between the range of €20 - 25 million. While that is a lot cheaper than Oblak, Butland would also be a downgrade for Chelsea when compared to the likes of Courtois. Butland has been a stand out performer for Stoke City and will only improve at Chelsea.

According to reports from multiple sources like Bleacher Report, Jack Butland is expected to be one of Chelsea's target to replace Thibaut Courtois. Alan Myers of Sky Sports has also reported that the Blues will be looking to buy Butland and would not be looking to get into the race to sign Pickford.
