Chelsea defender undergoes Crystal Place medical ahead of £20million move

Crystal Palace are closing in on the signing of Marc Guehi from Chelsea and the fee could reach as high as £20million.

The England Under-21 star is having a medical today and is set to sign a five-year contract with the South London club.

Guehi, 21, had an impressive season last term while on loan at Swansea, where he played 45 games and helped the Welsh side reach the Championship play-offs.

His expected signing will continue Palace’s flurry of transfer business this month after finally appointing a new manager in Patrick Vieira.

Winger Michael Olise, 19, has been poached from Reading for £8million, while third-choice goalkeeper Remi Matthews has joined on a free transfer.

New contracts are expected for defenders Joel Ward and Gary Cahill, but more signings are in the pipeline as sporting director Dougie Freedman rejuvenates an ageing squad.
