Middlesbrough have sounded out Feyenoord striker Romeo Castelen about a move to Teesside.
The 24 year-old favours a move to France and PSG, but Feyenoord are still waiting for a concrete offer to arrive from Parisians.
In the meantime, Castelen's agents have been contacted by Boro, Parma and Torino about his availability.
Feyenoord rate the striker in the £6 million class.
