It's well documented that Manchester United need to sign a centre back - even with Louis van Gaal's men only conceding 22 goals this season, which is the third lowest total in the Premier League.
Phil Jones, Jonny Evans and Chris Smalling are far too inconsistent to be considered long-term solutions for the Red Devils, leading to rampant speculation over moves in the transfer market.
Borussia Dortmund's Mats Hummels and Real Madrid's Raphael Varane have both been linked with moves to Old Trafford recently, with United seemingly prepared to spend big money in order to land a top centre back.
Paris Saint-Germain's Marquinhos is a more recent name on the agenda, according to the Daily Mail, with the Brazilian international impressing in France.
The former Roma defender may only be 6ft tall - which some may consider to be too small to play as a centre back - but he's earned a strong reputation based on his reading of the game and ability to bring the ball out of defence.
In an interview with this month's edition with FourFourTwo, Marquinhos was asked about interest from United back in 2013 when he was with Roma, and hinted that whilst there were talks with 'other clubs', moving to England isn't something at the forefront of his mind.
"The Premier League is watched around the world. There is even some concern in Brazil about children supporting English teams. We had some talks with some sides in the past, but I'm happy at PSG now," said Marquinhos.
