Earlier this summer Chelsea agreed to sell David Luiz, for a potential £50 million fee.
But with his impending arrival the future of his countryman Marquinhos has been thrown into doubt. The 20-year-old joined PSG last summer for a whopping fee of €31.4 million - but he has now admitted doubts over his future as a result of Luiz's arrival.
Barcelona are said to be interested, and Marquinhos has told reporters:
"I will talk with the club and my agent about my future because this will be a very important season for me. I have to say that David is a friend. He's a great lad and a great player. Besides, I think he made the right choice by committing to PSG but, when you see players like David Luiz arrive, it will be even harder for me."
Which has seen Manchester United being mentioned as an interested party. The club chased him last summer. They were keen on his signature last summer, his agent even confirming talks, while they need defenders. Rio Ferdinand is joining QPR and Nemanja Vidic is off to Inter Milan - leaving United bare on defensive options.
Marquinhos is a world-class defender in the making, but Barcelona seem very keen on his signature - but it appears there have been more developments in this story.
It is not being reported Barcelona, who reportedly made a €25 million plus Dani Alves bid for the player already this summer, have come back with a second bid for the player - which gives United a genuine gauge of the large cost it will take to lure PSG into a sale. Because the latest rejection was reportedly worth €35 million and Dani Alves.
Marquinhos is good, of that there is no doubt, but United now know that €35 million plus one of the best right-backs in the world will not be enough to pry him from Paris.
Whether that is out of their price range remains to be seen.
