Sam Byram is set to join West Ham in a stunning U-turn just 24 hours after agreeing a move to Everton, Football Insider sources understand.

The versatile Leeds star held talks with Everton over the weekend and indicated he was ready to join Roberto Martinez’s team after the Merseysiders’ bid was accepted by the Championship club on Thursday.

But West Ham made a late move for Byram on Sunday night and the 22-year-old has now decided to make the switch to east London instead of Merseyside.

Byram is set to travel to London on Tuesday and clinch a move that will cost the Hammers £3.5million plus add-ons.

West Ham have been struggling for a right back, with James Tomkins filling in this season due to the poor form of on-loan Arsenal star Carl Jenkinson.

Byram, who has been used at right midfield by Leeds in recent weeks, is seen as the long term option at right-back by Slaven Bilic and his staff.

The youngster was left out of the Leeds team that lost 2-0 to Sheffield Wednesday on Saturday, with his transfer to Everton pending.

But his next game is not set to be played in a West Ham shirt in what will be regarded as a major blow by Everton.

Byram’s exit was widely expected in the January window after Leeds failed with attempts to extend his contract, which expires at the end of this season.

Evans paved the way for Bryam’s exit by revealing 10 days ago that he was unsure whether the club’s prize asset will be at Elland Road beyond the end of the month.

Byram’s reputation is growing rapidly, and last week he was crowned the Championship PFA Fans’ Player of the Month for December, in which he scored three goals and grabbed an assist to help Leeds stay unbeaten during the month.
