Haaland's agent lists Man City, Bayern, Barca, Real as options

The 21-year-old has a contract with Dortmund until 2024, but his tally of 23 goals in 20 Champions League games for Dortmund and ex-club Salzburg has attracted Europe's top teams.

There is a release clause, reportedly for 80 million euros ($90 million), in Haaland's contract which becomes active in 2022.

Raiola has told broadcaster Sport1 there is "a great chance that Erling will leave" at the end of this season.

"Maybe this summer, maybe the summer after," Raiola added.

"He can - and will - take the next step. Bayern, Real, Barcelona, (Man) City - these are the big clubs he can go to.
