Borussia Dortmund are reportedly looking to receive a 'really huge' fee to sell Jude Bellingham next summer.
The England international has become an integral part of Dortmund's side, having registered 14 goals and 20 assists in 102 appearances for the club.
Bellingham demonstrated his importance to the German club in Wednesday's 4-1 Champions League win against Sevilla, with the midfielder providing Raphael Guerreiro's opener before finding the net himself.
Following the game, transfer expert Fabrizio Romano took to Twitter to say: "Get ready for a crazy, really huge price tag next summer."
Although the 19-year-old is under contract until 2025, a number of Europe's biggest clubs are set to battle it out for his signature.
Chelsea, Manchester City, Liverpool and Real Madrid are all believed to be interested in securing the services of the Englishman.
In the short term, Bellingham will be fully focused on one of Germany's biggest games in the football calendar, with Dortmund set to face Bayern in Der Klassiker on Saturday.
