Gudjohnsen told the Daily Mail: “I joined Barcelona to be part of the club’s triumphs but it is not easy for me when you look at the club’s forward line and see all the big names there.
“Each minute has been a special test for me but to sit on the bench is not the most desirable experience for a player.
“I don’t think I have failed in Spain but perhaps I have not totally won the confidence of the coach. If I leave then my ideal idea would be to return to British football.
“If Barcelona decide to place me in the market then I need to study all the details. But a perfect choice for me will be a club that plays in the Champions League.
“Obviously Manchester United fit that category.”
