Manchester United will rebuff any approaches for Marcus Rashford or Paul Pogba this summer but face a serious fight to prise Jadon Sancho from Borussia Dortmund, with the German club adamant they will not be bullied into selling the rising England star.

Ole Gunnar Solskjaer considers Rashford and Pogba as integral to his long-term plans and the Norwegian, whom players and staff believe is close to being confirmed as United manager on a permanent basis, has no interest in losing either.

Both players have been linked with Barcelona and Real Madrid but United are in talks with striker Rashford over a lucrative new long-term contract and midfielder Pogba - who claimed last week that it would be a “dream” to play for Real - has over two years left on his existing deal and an option on the club’s side to extend that by another 12 months.

Solskjaer wants to strengthen his squad, not lose key assets, but Dortmund are adopting a hardline stance over Sancho, a leading target for United. The Bundesliga side are insistent the 19-year-old will not leave this summer and it could take an offer of around £100 million or more for them to even countenance selling.
