The Hammers assistant coach has expressed his belief that the midfielder is "too good a player to be sat on the outside" at Old Trafford
Stuart Pearce has hinted that Jesse Lingard could still join West Ham in January, claiming the Manchester United star "holds all the cards".
Lingard returned to United in June after a successful six-month loan spell at West Ham, where he scored nine goals in 16 Premier League games to help David Moyes' side qualify for the Europa League.
Moyes openly admitted that the Hammers were eager to sign the 28-year-old on a permanent deal, but they failed to do so before the summer deadline, and his assistant has suggested that the midfielder made the wrong choice over his future.
