Officials at Manchester United are growing increasingly frustrated at what they see as deliberately placed bogus transfer stories attempting to generate interest in players and increase prices.
Last week, Portuguese media linked the club with a move for Wolves forward Raul Jimenez, a story which a United insider described as 'utter nonsense'.
There is a belief at Old Trafford that agents feel the club are an easy target, and that if they can get them linked with certain players it will be in their own interests. 'The Jimenez story making the gossip page on the BBC's website certainly did not help,' the source added.
