Manchester United manager David Moyes has suffered another setback in his search for a midfielder after Atletico Madrid midfielder Koke signed a new contract with the mattress makers which will see him remain at the club till 2018.

Express Sport is reporting that Koke now has a £50 million release clause in his contract meaning that Manchester United would face an uphill battle in trying to get the 22-year-old Spaniard to leave the Vincente Calderon.

This new development is yet another blow to Moyes who has been travelling Europe in search of new players to sign for United.
