Birmingham City star Jude Bellingham is set to become the most expensive 17-year-old in the world.

The Englishman has completed a medical at Borussia Dortmund, according to Sky Sports.

The German giants are now entering the final stages of the transfer.

Bellingham is set to sign for £26 million, with a significant portion of the fee guaranteed up front to Birmingham.

The player was wanted by Manchester United and other teams in the Premier League, but he has chosen to follow in Jadon Sancho's footsteps by joining Dortmund.

The England under-17 skipper believes he will have the best chance to compete for a first team place at the Bundesliga side.
