Fulham full-back Ryan Fredericks will be new West Ham manager Manuel Pellegrini’s first signing next week, after agreeing a four-year contract.

The Hammersmith-born defender’s contract expires at the end of this month and he had failed to reach an agreement about a new deal with the Craven Cottage club, who are back in the top flight following last Saturday’s Championship play-off Final victory over Aston Villa.

Fredericks, 25, wanted to become the club’s highest earner, currently midfielder Tom Cairney who is thought to be on around £40,000 per week. Fulham’s offer fell short of that figure.

West Ham have also been interested in Cairney and David Moyes watched the Scotland star several times during his six months as West Ham boss.

A move for Cairney (below) though, could be more tricky given that he is club captain and will be crucial to Fulham’s Premier League plans.

Fredericks is an attacking full-back who will inject some pace down the team’s right flank. Pablo Zabaleta, 33, was West Ham’s regular right-back last season and proved to be one of the team’s most consistent performers. But with Sam Byram tipped to move on, West Ham needed competition in that position.

Fulham, meanwhile, look likely to promote Cyrus Christie to first-choice right-back. The 25-year-old joined from Middlesbrough last January but his opportunities since have been limited.

West Ham are also poised to announce Mario Husillos as their new head of recruitment. A trusted confidant of Pellegrini, the 59-year-old Argentine worked with West Ham’s new boss when the pair were at Malaga.

Husillos returned to the Spanish club last January but was unable to prevent them being relegated.
