West Ham must sign a replacement for Ryan Fredericks if they are to let him leave in January.

That is according to former Sunderland and Aston Villa striker Kevin Phillips, speaking exclusively to Football Insider correspondent Dylan Childs about the possibility of the 28-year-old leaving the Irons in 2021.

Fredericks is fast approaching the final 18 months of his contract at the London Stadium and the club may look to cash in on the full-back next year rather than lose him on a free.

The summer-of-2018 signing has fallen down the pecking order at West Ham of late with Vladimir Coufal clearly David Moyes’s preferred choice at right wing-back.

The emergence of highly-rated defender Ben Johnson could persuade Moyes into parting with the former Fulham man who has recently been sidelined through injury.

When asked by Football Insider if it would be a mistake to sell Fredericks in 2021, Phillips said:  “It would only be a mistake, letting Fredericks go, if they do not replace him.

“He is a good backup player. When he has been called upon he has not really let them down.

“You always have to be a bit careful. If you are going to let a player like him go you have to have someone else lined up but David Moyes is not stupid, he will know that.

“I would certainly not be letting him leave without a backup. If they lose Coufal you could be in trouble.

“Fredericks has shown that he can play at Premier League level so I would be careful.”
