Borussia Dortmund star Marco Reus's agent was spotted at Manchester United's game against Manchester City this weekend.

The German attacking midfielder is out of contract at the Bundesliga club at the end of the season.

Per the Daily Mail, Al-Nassr in Saudi Arabia are among the many teams chasing Reus on a free transfer.

Reus's agent Dirk Hebel was pictured at Old Trafford for Manchester United's 2-1 derby day win over City alongside colleague Darren Freeman.

There is no suggestion about which club Reus may be looking at for his next team.

He has been linked to both United and City, along with other Premier League clubs, in the past.
