West Ham boss Manuel Pellegrini is looking to significantly improve the defensive options he has inherited at the London Stadium and is keen to raid a relegated side.

The Hammers have been widely linked with the services of Swansea City duo Alfie Mawson and Lukasz Fabianski, reportedly already seeing a bid rejected for the duo, but continue to hunt the pair.

Sky Sports report West Ham remain in talks with Swansea, relegated to the Championship in the 2017-18 season, as they push to bolster their defensive line with the acquisition of the duo.

Pellegrini has already drafted in full-back Ryan Fredericks on a free transfer from newly-promoted Fulham and sees Mawson as the ideal central defensive partner to young ace Declan Rice.

Fabianski, meanwhile, is the leading candidate to be West Ham’s first-choice stopper for the new Premier League season after the Hammers elected not to make Joe Hart’s loan spell from Manchester City permanent.
