Manchester United have been handed a boost in their attempt to sign Paris Saint-Germain defender Marquinhos after the centre-back said he will decide his future in the next few days.

The Express reports the Brazil international has been linked with a move to Old Trafford after the Ligue 1 champions sealed a £50m deal for David Luiz from Chelsea. The report suggested that United could reignite their interest in the 20-year-old. Barcelona are also in the frame for his services.

Marquinhos is part of Luiz Felipe Scolari's squad for the World Cup. The centre-back stressed that he was focusing on summer with the national side and will soon make a decision on his future at Parc des Princes.

"Now my thoughts are on the Brazil side and I leave any answer or decision to be taken in the hands of PSG, who are the ones that have my contract and will decide my future," Marca quoted Marquinhos as saying.

"In the next few days, I will sit down to see exactly what the situation is with my club, my business and my family. We will decide what is best for my future."

"As a player, I try to learn all I can. I've just turned 20 years old. I'm very happy with my career", he added.

Marquinhos made 29 appearances in all competitions for the French champions during the 2013/14 campaign. The arrival of Luiz is likely to see his first team appearances being limited next season.

The Brazilian defender is aware that the players coming to PSG will make it difficult for him to cement a place in his side's starting XI.

"When I see the players that are coming, I realise it will be difficult [to compete for a first-team spot]. I have a contract until June 2018. Let's see, my agent will talk with the club about my future as this season is very important to me," Marquinhos said, as quoted in the Express.

United have allowed Nemanja Vidic and Rio Ferdinand to leave the club as free agents. The Red Devils are in need of a centre-back to fill the void left by the departure of their two ageing stars. The addition of Marquinhos is likely to bolster Louis van Gaal's squad.
