Manchester United have been offered the chance to sign £50m-rated Jerome Boateng from Bayern Munich. United have held talks with Barcelona for defender Yerry Mina but are considering other options.
Matt Judge, United's head of corporate finance, was at their London offices on Thursday but is understood to have held talks with Barcelona over 25-year-old Mina, who also has interest from Everton and Lyon and is valued around £30m.
Barcelona also need to sell the Colombian to make room on their non-EU quota for Arturo Vidal who is poised to join from Bayern Munich for £27m.
The 29-year-old Boateng saw a move to Paris Saint-Germain stall this week and Bayern are open to selling the Germany international.
Boateng did not enjoy a good World Cup and age is against him as United consider Bayern's asking price of £50m.
Similar logic applies to Toby Alderweireld at Tottenham with the London club wanting over £50m for the Belgian while Leicester insist Harry Maguire is simply not for sale.
United continue to look at options to offset their spending with Marcos Rojo a target for Everton, Paris St Germain and Zenit St Petersburg.
While Anthony Martial has been floated as an option for Bayern, he is not a player they wish to pursue at this stage.
United keeper Joel Pereira, meanwhile, has completed his move to Vitoria Setubal on loan.
Leicester City have made an enquiry for Adnan Januzaj. The 23-year-old Real Sociedad winger is valued around £15m and Manchester United have a buy-back option.
