Alex Telles's agent has reportedly arrived in the United Kingdom to thrash out terms with Manchester United over the full-back's proposed move from Porto.
The 27-year-old enjoyed another impressive campaign for the Portuguese giants last season and has also been touted as a target for Chelsea.
According to The Mirror, United are further down the line than Chelsea as Telles's representative is now in talks with the Red Devils over a possible switch.
United are said to be eager to strengthen in the left-back area due to concerns over Luke Shaw, with Real Madrid's Sergio Reguilon another option.
The report suggests that the defender's agent intends to push discussions along at a quicker pace in the hope of getting a deal in place soon.
Telles, who made his senior debut for Brazil last March, is thought to be available for €25m (£22.8m).
