Manchester United boss Louis van Gaal won't get a clear run at Porto fullback Bruno Martins Indi.
TMW says United will have to fend off competition from Europe's heavyweights in order to sign Martins Indi.
The Dutch star has been tipped to link up with former international boss Louis van Gaal again in the near future, but a long list of teams are after his signature.
United are reportedly now competing with Bayern Munich, Barcelona, Roma and AC Milan for the 23-year-old.
Martins Indi only joined Porto in January for £5.7million and is now thought to be worth around £19million.
