Manchester United are reportedly currently the only serious bidder for Erling Braut Haaland, with the striker expected to leave Borussia Dortmund during next summer's transfer window.

The Norway international will allegedly have a £63m release clause in his contract ahead of the 2022-23 campaign, and a host of clubs, including Manchester City, Barcelona, Real Madrid, Chelsea and Bayern Munich, continue to be credited with an interest in his services.

Haaland's agent Mino Raiola recently suggested that Man United were not in the running for the 21-year-old, but the Red Devils continue to be credited with an interest in his services.

According to Bild, the 20-time English champions are currently the only 'serious bidder in Haaland poker'.

The report claims that Barcelona's financial problems will make it difficult for them to sign the centre-forward, while Real Madrid and Man City both have other priorities next year.

Chelsea, meanwhile, re-signed Romelu Lukaku in a club-record deal over the summer, and it remains to be seen whether the Blues will bring another high-profile forward to Stamford Bridge next year.

Haaland has again been in impressive form for BVB during the current season, scoring 17 times and registering five assists in 14 appearances in all competitions.
