Theo Walcott trusts Arsène Wenger to steer Arsenal to success this season.

Not for the first time the Gunners have been tipped to drop out of the Premier League's top four and the harbingers of doom have grown louder since Cesc Fabregas left for Barcelona this week.

But with Wenger looking to bring in replacements for this summer's outgoing players having already added Gervinho, Alex Oxlade-Chamberlain, Carl Jenkinson and Ryo Miyaichi to his squad, Walcott is staying positive.

"Well, I am smiling right now so I am very positive," he said following Arsenal's 1-0 win over Udinese.

"Tuesday's result was very positive and hopefully it will help the fans as well. I am sure the boss has got players coming - I don’t know - but if you sell one of your best players I am sure he has got options coming in.

"But the mood is very good. We got a very good result at Newcastle I thought, especially going down to ten men. A clean sheet was very good and we had young players come on and gain experience in the Champions League. We have another very tough game at the weekend and then head out to Italy."

With Robin van Persie and Samir Nasri suspended on Tuesday, Walcott stepped up on the night and was Arsenal's most dangerous player when they went forward, capping a promising display with the only goal of the game. At 22, he is ready to take on more responsibility.

"I was the oldest player on the table for dinner at Newcastle at 22 years old," he recalled. "It was quite funny but I’ll do anything I can do to help the young players coming through. I have been around for a long time so I know what it’s all about and if I can help anyone out I will happily do that.

"This team has always been known for being so young but we cannot use that excuse anymore. We need to win something and that’s the most important thing.

"It is important to have a mixture of experience and young players but the boss knows what he is doing. He has some great players that he has picked up and we didn’t know where they came from. Only time will tell what the boss will do."
