With the World Cup finished, the summer transfer window is now starting to heat up, as managers look to bring in additions to their squads ahead of the start of the 2018/19 campaign.

Plenty of big names have been linked with switches, and with that in mind, we’re taking a closer look at some of Europe’s most in-demand stars.

Our next player analysis is Borussia Dortmund’s teenage star Christian Pulisic…

Linked to: Real Madrid, Chelsea, Liverpool and Bayern Munich

Price tag: £70 million

“He’s a fantastic skilled boy, and it’s not a surprise to see. He’s a smart player.” It’s fair to say Jurgen Klopp is a fan of Dortmund wonderkid Pulisic.

The American teenager was impressive in helping the Bundesliga side beat Klopp’s Liverpool in a pre-season friendly on Sunday, scoring twice in the International Champions Cup clash.

But it’s not just the Liverpool boss who has been impressed, with Real Madrid, Bayern Munich and Chelsea all rumoured to be interested in signing the 19-year-old.

Pulisic is yet to reach 100 senior appearances at club level, but already clubs are taking note.

Could Pulisic follow in the footsteps of Robert Lewandowski, Mats Hummels and Mario Gotze and switch Dortmund for Munich? Bayern are understood to see the youngster as the ideal replacement for the ageing Arjen Robben and Franck Ribery.

But European champions Real Madrid have been alerted to his excellent performances, and with Cristiano Ronaldo gone and Chelsea digging in their heels over Eden Hazard, Pulisic could be a possible solution.

Chelsea, Klopp’s Liverpool and Manchester United have all registered an interest in the Dortmund star, but the presence of both Real and Bayern mean a Premier League switch is unlikely.

Christian Pulisic (l) has admirers in Germany, Spain and England.

His on-field quality, coupled with the American market he would entice to his new club, makes Pulisic one of the most in-demand youngsters in the world right now.

Though Pulisic seems perfectly happy to continue his upward trajectory at Dortmund, should one of the big clubs come calling, it may be difficult for both club and player to say no.
