Manchester United are persisting with their pursuit of Marquinhos, but they look to be fighting an uphill battle, with Paris Saint-Germain keen to keep their defender, according to reports from the Daily Mail.
The Red Devils are understood to have been pushing a move over the past week for the 20-year-old, with numerous conversations between themselves and the Parisians having taken place.
However, the Ligue 1 champions have been reluctant to discuss a sale, which has put United on the back foot.
PSG are adamant that they will not lose their youngster before the looming transfer deadline, yet the Premier League giants are confident that they can work out a deal for him.
Marquinhos himself has only been a PSG player for 18 months, but his role in Laurent Blanc’s first-team has been a minimal one so far.
Compatriot, and senior team-mate, Thiago Silva is considered to be the top centre-back at the Parc des Princes, and the arrival of David Luiz from Chelsea last year has seen the pair hold down a regular partnership at the expense of the starlet.
