Manchester United are said to be growing in confidence that they will be able to strike a deal for Paris Saint-Germain defender Marquinhos this summer.
According to David McDonnell of the Daily Mirror, the Red Devils have made the Brazilian international their priority acquisition at the back, and they are said to be hopeful of completing a move for around £50 million.
"PSG are reluctant to lose Marquinhos, but United are said to be confident they can strike a deal to bring the versatile defender to Old Trafford," added McDonnell. "[Jose] Mourinho has doubts over United defensive duo Chris Smalling and Phil Jones, criticising them this week for ruling themselves out of the Manchester derby.
