Arsenal have started negotiations with Borussia Dortmund over a potential £51m move for Marco Reus, according to multiple reports.

Arsenal have identified the 28 year old versatile frontline player as a replacement for Alexis Sanchez should the Chilean leaves Emirates at the end of the season.

Reus’ proposed contract in north London would be worth £6.8m annually on a five-year deal.

And Arsenal are prepared to break their transfer record to land him if they lose Sanchez.

The Chilean has 18 months left on his contract and is reportedly ‘unsure’ about his Arsenal future.
