Manchester United are ready to make Borussia Dortmund defender Mats Hummels their number one transfer priority after Paris Saint Germain confirmed Marquinhos would not be sold.
New boss Louis Van Gaal is expected to sign at least one high profile centre-back this summer, following the departures of Nemanja Vidic and Rio Ferdinand. Both have left United after their contracts expired, and Ferdinand is now a free agent while Vidic has joined Inter Milan.
Marquinhos at PSG
But several names have been mentioned in conjunction with United. Hummels has always been among the frontrunners, but the Old Trafford club have also reportedly been considering PSG's Marquinhos and Atletico Madrid's Miranda.
But the Daily Express reports that Hummels will now officially become United's top transfer target in the wake of comments from Laurent Blanc.
"Marquinhos isn't going anywhere, that's for sure," Blanc said. "He won't be leaving. We're counting on him."
The young Brazilian defender may have been fearing for his place after Blanc splashed the cash to bring in David Luiz. The former-Chelsea star will partner international teammate Thiago Silva at the heart of their defence.
Hummels: Does he want to move?
The Germany international hinted that he'd be open to leaving Borussia Dortmund earlier this season, although coach Jurgen Klopp is thought to be desperate to keep him in the Bundesliga.
He struggled with injury for much of the season and only made 23 Bundesliga appearances as Borussia Dortmund finished second in the league to Bayern Munich.
His partnership with Nevan Subotic was one of the best in Europe, until injuries split them.
With Ferdinand and Vidic gone, there's no clear number one centre-back at Old Trafford. Johnny Evans, Chris Smalling and Phil Jones have failed to establish themselves as reliable options for the long-term, which has led to an expectation that Van Gaal will strengthen at the first opportunity.
The Dutchman has also inevitably been linked with a couple of his Netherlands defenders. Bruno Martins Indi, who was tested for concussion after his collision with Tim Cahill against Australia, is one of the top contenders.
