Manchester United are closing in on a deal for highly-rated Porto full-back Diogo Dalot, according to reports in Portugal and England.
After finishing runners-up in both the Premier League and FA Cup, Jose Mourinho has set about trying to bolster his squad for an improved challenge next season.
Among United's targets is 19-year-old Porto full-back Dalot, who is preparing to switch the club he joined in 2008 for Old Trafford.
Reports claim there is a good chance of a deal being reached between United and Mourinho's former club instead of using the 20 million euros (£17.5 million) release clause that soon becomes active.
Dalot, a right-back capable playing on the left, has only made a handful of senior appearances for Porto, but is considered a huge talent and has attracted interest from many teams across Europe.
