Manager Arsène Wenger has admitted that he has not shut the door on former striker Thierry Henry and has been keeping in touch with the Barcelona player.
Press speculation has been growing over a possible return for the mercurial Frenchman, and Wenger admitted that whilst it is was unlikely, one should never say never in football.
Wenger said: “In our situation you can never say never. He only left last year and I think Thierry is disappointed because things haven’t gone as well as he would have liked them to go.
"I still feel he is a world-class player and I think he will prove in Barcelona that he is one of their better players.
“I had a chat with him not long ago. He watches every Arsenal game and I watch Barcelona when I can because I’m interested to see how he looks, whether he has found his sharpness and what position he is playing. I gave him my view about his game.
“Thierry is an efficient goalscorer but they have two or three players in there. His success has been damaged a little because Ronaldinho has not turned up this year and Thierry was the one who could play left wing.
“That’s where he has played but that’s not his preferred position or where he is most efficient.
“The whole team didn’t work at Barcelona. They have never been in the race for the championship. Then every player gets a little bit devalued. But he still has a lot to offer as a player.
“Things change quickly when you have talent and he has plenty. My interpretation is that he is happy in Barcelona.”
