Vieira is on the Marc

PATRICK VIEIRA is set to make his third signing at Crystal Palace when £20m Chelsea defender Marc Guehi joins the club this week.

Guehi had a medical at Palace yesterday after agreeing a five-year contract with the Eagles.

Chelsea were reluctant to lose Guehi (inset), who is regarded as a huge prospect, but the England Under 21 international wanted regular first-team football.

Remi Matthews and Reading teen Michael Olise as Vieira’s new recruits, with more expected before the transfer window shuts.

As part of the deal, Chelsea have negotiated a sell-on clause for Guehi and the right to match the terms of any future sale.

The 21-year-old spent last season on loan at Swansea, who reached the Championship play-off final. Guehi potentially plugs a big hole for Palace, who are not expected to offer Scott Dann a new contract and have yet to re-sign Gary Cahill. They have, however, tied defender Joel Ward, 31, down on a new two-year deal. The right-back has spent the last nine seasons at Selhurst Park.
