Thomas Tuchel’s sour relationship with Borussia Dortmund could dent Chelsea’s chances of signing Erling Haaland, in a boost to Man Utd.

Bild claim the German left Dortmund on bad terms and club chiefs are reluctant to sell to a side coached by their former manager.

The report adds that it’s ‘very unlikely’ the Bundesliga outfit will allow Haaland to seal a move to Stamford Bridge this summer.

Although Tuchel won a German Cup at Dortmund, his time there is best-remembered for the bust-ups he had.

There were disagreements with senior players, including Mats Hummels, Neven Subotic, Jakub Blaszczykowski and Roman Weidenfeller.

While Tuchel also clashed with former chief scout Sven Mislantat, who would later work for Arsenal.

He was then sacked by Dortmund with chief executive Hans-Joachim Watzke saying he was ‘worn out’ dealing with the manager.
