Borussia Dortmund are willing to spend big on Manchester United midfielder Hannibal Mejbri.

The youngster has just completed an impressive season-long loan with Birmingham City and returns to United uncertain of his future.

The Manchester Evening News says Dortmund are among several European clubs keen.

And they'd be willing to splash out as much as £15m to prise Hannibal away from United this summer.

United manager Erik ten Hag is expected to give Hannibal preseason to prove himself before making a final decision.
