Manchester United have been told they must raise their £15 million offer for Aymeric Laporte by a further £5 million if they are serious about signing the Athletic Bilbao defender at the end of the season.
According to the Daily Star on Sunday, the Red Devils wanted to sign the France U21 international during the January transfer window, but have now accepted that Ernesto Valverde will not allow the player to leave San Mames until the summer.
Louis van Gaal is planning a complete overhaul of his defence at Old Trafford, and Laporte has been identified as the next piece of his jigsaw in what will be a new-look Manchester United rearguard next term.
The 20-year-old has a £20 million buyout clause written into his current deal with the Basque club, and could follow former team-mate Ander Herrera to the Theatre of Dreams if the Premier League giants agree to meet the talented stopper's valuation.
Laporte has become a key player for Athletic Bilbao over the past couple of seasons, so fans will be disappointed to see him leave Spain for a new challenge in England in the latter part of 2015.

His departure could come just 12 months after Herrera joined Manchester United in a £28 million deal, although he's struggled to make much of an impact under Van Gaal after struggling to find his fitness and form.
