According to El Partidazo de COPE, Manchester United have hit a bump in their pursuit for Sergio Reguilon, with Real Madrid insisting on a £27million buy-back clause.

Last weekend Sergio Reguilon made his debut for Spain, after impressing on loan at Sevilla last season.

Despite his good form, the 23-year-old is not in Madrid manager Zinedine Zidane’s first-team plans.

Ole Gunnar Solskjaer is keen on a £27m move, but the United board don’t want to include a buy-back clause.

The Premier League club feels such clause could come back to haunt them in the future.

Serie A side, Napoli, are also keeping an eye on Reguilon’s situation, but United are the front-runners despite the current stand-off.
