Arsenal will keep close tabs on Marco Reus this season, Football Insider sources understand.

The Gunners have had a long-standing interest in the £35million-rated Germany international and are poised to closely monitor him in the coming months.

Sources have told Football Insider that Arsenal scouts have been asked to closely watch Reus as they mull over a possible move for him.

Arsene Wenger is a big admirer of Reus and was interested in signing him in the summer of 2014 but the player stayed at Borussia Dortmund and agreed a new contract.

His deal runs until 2019 but the attacking midfielder is on the radar of some of Europe’s biggest clubs, including Real Madrid and Barcelona.

Reus, 26, has scored 59 goals in 133 matches since joining Dortmund from Borussia Mochengladbach in 2012, including six goals in 11 Dortmund appearances this season.

He has been used predominantly on the right wing by new Dortmund manager Thomas Tuchel in 2015/16, but he can play in any of the three positions behind the centre-forward and has also been used as the attack spearhead on a number of occasions.
