Alfie Mawson
Swansea defender Mawson has been one of Swansea’s stand-out players this season after joining the Welsh outfit from Barnsley last summer.
Making 27 appearances for Swansea last season, the 23-year-old was crucial in helping the Swans escape relegation and quickly developed a reputation as a goalscoring defender in the opposition box with four strikes.
West Ham struggled at the back last season and following the flop signing of Euro 2016 winner Jose Fonte and the long-term injury to Angelo Ogbonna, Mawson should be brought to the London Stadium to partner Winston Reid.
