Manchester United are on alert with news that Marco Reus could leave Borussia Dortmund next summer.

The Express is reporting that the 26-year-old winger is playing his last season in Germany before moving on at the end of the current campaign.

United have previously been linked with Germany international Reus, most recently when they pursued his services in the recent summer transfer window, but did not want to part with £60million.

Reus is contracted with Dortmund until the summer of 2019 but is looking to leave the Westfalenstadion and is expected to again be the subject of interest from United, as well as Spanish giants Real Madrid, who were also circling in the summer.
