#4 Jack Butland (Stoke City to Chelsea)
With Thibaut Courtois going AWOL from Chelsea training in a bid to force a move to Real Madrid, Chelsea have begun to contemplate options for his replacement, as the Belgium international has just one year left on his contract, and the club would be keen to sell him now rather than lose him for free next season.
Jan Oblak was touted as the prime candidate to replace the man he replaced at Atletico Madrid, however, he has a release clause of £89m, which the London club deem too expensive, hence the decision to make the Stoke City keeper their number one target.
The 25-year-old Butland is one of the highest rated England goalkeepers, and made the 23-man squad to the World Cup despite being relegated last season with Stoke City.
He has started life in the Championship, playing all 90 minutes in the 3-1 defeat to Leeds United at Elland Road. However, his status could soon change, as Chelsea are very much interested in bringing him back to top-flight football.
