Bayern Munich stars Franck Ribery and David Alaba have urged team-mate Jerome Boateng to remain at the club this summer amid interest from Manchester United.Jose Mourinho has turned his attention to the German international as he looks to bring in a new defender before the start of the Premier League season.United have opened talks with Bayern, who want £45million for the 29-year-old, but the Red Devils are keen to negotiate that fee in a bid to bring it closer to the £40m mark.

I hope he’ll stay with us because he’s an important player. To me, he’s one of the best central defenders in the world.’ Goalkeeper Manuel Neuer also insisted that Boateng would be ‘missed’ at Bayern and Alaba admitted he felt the same way.‘We’d all be sad,’ said the Austrian. ‘He’s a world-class player, one of the best in his position.’ Jose Mourinho has pleaded with United chief Ed Woodward to bring in some new to Old Trafford before Thursday night's deadline.A new centre-half remains the priority and Mourinho is banking on Woodward delivering one in time for their opening game against Leicester on Friday night.Boateng — a half-time substitute for Bayern in their friendly victory over United on Sunday — emerged as an alternative to Harry Maguire who is being priced out of a move by Leicester. United also considered Toby Alderweireld and Yerry Mina. RELATED ARTICLES Previous 1 Next ‘The best defender in the world’: Mohamed Salah and Virgil...
