Manchester United boss Sir Alex Ferguson has revealed his frustration in his attempts to sign prolific Arsenal striker Robin van Persie.
The Netherlands international has entered the final year of his Gunners contract and has declined an offer to extend his stay at Emirates Stadium.
Ferguson has revealed he has made an approach for last season's Premier League top goalscorer. It is understood Arsenal are demanding a fee in excess of £20million.
"We've made a bid – they [Arsenal] have been trying to negotiate with other clubs. I don't have a gut feeling about it. We can't get a breakthrough with Arsenal," said the experienced manager.
Van Persie, who moved to Arsenal from Feyenoord in 2004, has suggested he would favour a move away from the club during the close season in his quest for silverware.
Football betting news reports than reported that Arsenal were considering resisting offers for the Dutchman and risk losing him on a free transfer next summer. Ferguson admitted he does not know their current stance.
"I don't know what Arsenal's thoughts are because they're not giving anything away. It's difficult to say why they're operating this way. I can't give you any more information," he added.
"We just have to persevere. We are trying our best and hopefully it will come our way but there's no progress at this moment in time."
Van Persie scored 41 goals in 53 games for club and country last term and picked up a number of personal accolades, United’s premier league odds would rapidly improve if they snapped up the talented forward.
United face competition from Turin giants Juventus for the 29-year-old, but Manchester City boss Roberto Mancini has revealed the Premier League champions are out of the running.
Van Persie is likely to line up for the Gunners in their season opener at home to Sunderland on August 18, should a suitable bid fail to materialise.
