Athletic Bilbao have confirmed that midfielder Ander Herrera has paid his own buyout clause in order to facilitate a move to Manchester United.
The 24-year-old's proposed move to Old Trafford appeared to hit a stumbling block when the La Liga club rejected a bid of around £29m this week.
However, the transfer is back on after the Spanish club confirmed that Herrera has bought out his contract, which contained a release clause in the region of £30m.
Reports have claimed that Herrera has already passed a medical and agreed terms with the former Premier League champions.
The move seems all but confirmed after Herrera changed his Twitter profile to a photo of him standing alongside Sir Bobby Charlton holding a United shirt.
