Borussia Dortmund have joined the battle for Arsenal attacker Alexis Sanchez.

The Gunners are resigned to losing their forward with his contract expiring next summer.

Don Balon says Dortmund are now a surprise new contender.

Following the summer sale of Ousmane Dembele to Barcelona, Dortmund want a new star player in their ranks.

Alexis has offers on the table from Manchester City, PSG and Bayern Munich at this stage.

But Dortmund have identified Sanchez as a key target and are looking to pounce.
