Theo Walcott, who scored a brilliant goal during Arsenal's 3-0 win over Wolves, says he feels like a "totally different" man after coming out of the shadow of his recent injury problems.

"I am a totally different Theo Walcott now. We are playing great football and it's nice to be part of that and not on the treatment table," ESPN quoted Walcott as saying.

Walcott, who has lately been in formidable form and has scored three goals in the Gunners' last four fixtures, has also registered his name in the Three Lions' squad for the 2012 European Championships in June.

The 23 year old winger gives all the credit for his recent form to his improved fitness over the past few months.

"I'm 23 now and I am still growing. I am not afraid of getting hurt. A few years ago I had shoulder injuries, ankle problems and back problems and that was just me learning the other side of the game," reported Walcott as saying.

Meanwhile, Arsenal are reportedly trying to sign Walcott, whose contract expires in 2013, for another four years, according to a second report.

According to the report, Walcott, who has put all his contract talks on hold since December, wants to leave the Emirates this summer. Although the 23-year-old winger has refused to publically discuss his future at Arsenal, it is believed that Walcott (who is being offered a revised salary of £80,000 per week by the club) wants a weekly wage of £100,000.

Several clubs including Manchester City, Chelsea and Liverpool are reportedly keeping a close eye on Walcott's contract talks with the Gunners so that they can make a move on the talented English winger if he decides to quit Arsenal.

However, Arsenal manager Arsene Wenger, who believes Walcott to be one of his top players, will not consider him leaving the club so easily.

"Theo is playing very well. He has improved his technical level a lot, his links with other players and his calmness in front of goal. He is developing very well. It is something I will look to sort out very early. To say that I am always confident, yes I am. We want to keep our best players," reported Wenger as saying.
