Manchester United allegedly remain convinced that they will sign Porto defender Alex Telles this summer.
The Premier League giants are favourites to win the race for the attack-minded left-back, who has less than a year remaining on his contract.
While United would have preferred to have already finalised a deal, Porto insist that they want to recoup at least £22.5m for the Brazilian.
Nevertheless, Italian journalist Fabrizio Romano claims that United officials are confident of eventually making the breakthrough in negotiations with their counterparts at the Portuguese side.
Telles would likely move ahead of Luke Shaw and Brandon Williams should he make the switch to Old Trafford before the end of the transfer window.
The 27-year-old has started each of Porto's two league matches this season, contributing two goals and one assist.
