Marco Reus's agent is seen at Manchester United for the derby against City

Marco Reus’s representatives were spotted at Saturday's Manchester derby as the Borussia Dortmund star weighs up his future.

Dortmund favourite Reus is out of contract in the summer and has confirmed he is considering his options ahead of a possible free transfer departure in the summer.

MailOnline revealed Al-Nassr, who signed Cristiano Ronaldo this month, are keen for Reus to become the next European big-name to follow him to Saudi Arabia.

Al-Nassr hope Reus, 33, will snub Premier League interest to join them after 11 years at Dortmund.

Reus’s agent Dirk Hebel, who was pictured at Old Trafford for Manchester United's dramatic victory over City alongside colleague Darren Freeman, told German publication Bild following the emergence of Al-Nassr’s interest: ‘It is quite normal that other clubs are interested in a player like Marco, whose contract expires in six months.

‘Marco has always emphasized how much BVB is close to his heart, but also that he wants to continue playing football. So it's only natural that we have to look at other options.’

Reus himself said on his future: ‘That's what I have an agent for – to take care of these things.

‘Of course you look ahead. I still have half a year left on my contract, I have to think about it. We will have talks and see in which direction it goes. We'll see what the future brings.’

Reus has been linked with both United and City, among others, in the past but proved too hard to prise away from his hometown club.

However, his potential free agent status has renewed his admirers’ hopes and cast fresh doubt over his future.
