Manchester United have hardened their stance on Paul Pogba by intimating privately that they value the midfielder at more than £150 million, sources have told ESPN FC.

The France international has suggested he would like to find a "new challenge" this summer amid interest from Real Madrid and Juventus.

Manager Ole Gunnar Solskjaer said on Wednesday United will not be bullied into selling Pogba after a series of public statements from his agent, Mino Raiola.

The World Cup winner, 26, has three years left on his contract and sources have told ESPN FC that United believe he is worth in excess of £150m in line with the spike in the transfer market following Neymar's £198m move from Barcelona to Paris Saint-Germain in 2017.

Pogba arrived in a then world record £89.3m deal from Juventus in 2016. After travelling to Perth as part of United's preseason tour squad, Pogba is set to play in the first game of the summer against Perth Glory on Saturday.

Perth Glory are suffering from a lack of numbers for the friendly and may be forced to field two 15-year-olds, one the son of coach Tony Popovic.

Meanwhile, sources have told ESPN FC that United have distanced themselves from a move for Mario Lemina. The midfielder is set to leave Southampton this summer.
