Schalke full-back Christian Fuchs is attracting interest from across Europe, with Manchester United scouts taking in Saturday's Ruhr derby reports skysports.com.
The 25-year-old Austrian international defender, has been in scintillating form in the Bundesliga this term, after arriving at Gelsenkirchen's Veltins-Arena in the summer on a four-year deal.
Red Devils boss Sir Alex Ferguson is believed to have sent Old Trafford scouts to Germany to run the rule over Fuchs, as he continues his search for a long-term replacement for Patrice Evra.
Schalke paid £4million for the former Bochum star, and if they are to be tempted into a sale, will surely be looking to make a profit on him.
Manchester United have also been credited with an interest in Fuchs' teammate Klaas-Jan Huntelaar in recent months, and it is understood that it was on a previous scouting trip for the Dutchman that the reigning Barclays Premier League champions were alerted to the left-backs potential.
However, United could face competition for the player's signature after it emerged that Italian giants Juventus, and their Serie A rivals Parma are also monitoring Fuchs' situation, with a view to making an offer.
