Manchester United will reportedly have to come up with an offer of €27m (£25m) in order to sign Porto defender Alex Telles before the end of this summer's transfer window.
The Red Devils continue to be linked with a move for the Brazil international, and Porto boss Sergio Conceicao recently conceded that the left-back could leave the club before the deadline.
United are said to be reluctant to pay over the odds for Telles considering that the 27-year-old's existing contract in Portugal is due to expire next summer.
However, according to Correio da Manha, the 20-time English champions will need to make an offer of €27m (£25m) in order for Porto to sanction a sale.
The report claims that both the defender's agent Pini Zahavi and Jorge Mendes, who is involved in the deal as an intermediary, will share 15% of any deal.
Meanwhile, it is alleged that Telles's former club Galatasaray are entitled to 10% of a transfer fee, meaning that Porto are facing missing out on a quarter of what United pay if the deal goes through.
The South American has reportedly already agreed terms on a five-year contract at Old Trafford.
