Manchester United have been invited to negotiate with Bayern Munich for Thiago Alcantara as the German giants look to create a bidding battle for the wantaway midfielder, sources have told ESPN.

Liverpool have been in contact with Bayern but have so far refused to meet the Bundesliga champions' €30 million valuation.

Thiago has informed the club he will not extend his contract, due to end in 2021, and is keen to move this summer.
