Arsenal manager Arsene Wenger has confirmed Theo Walcott's stomach operation was a success and is subsequently expecting the England star to return to action next month.

Walcott underwent and operation in Germany this week after having to withdraw during the warm-up of the Premier League clash against Stoke City on Sunday after complaining of pain in his abdomen.

The 24-year-old had already been confirmed to miss his country's crucial World Cup qualifiers against Poland and Montenegro in October.

Wenger told Sky Sports News: "Walcott had surgery and it went very well. He's coming back (from Germany) Thursday so it's what we expected there were no complications."

The winger is likely to return to the squad for the league match against Norwich on October 18 but will miss the Gunners' games against Swansea and West Brom as well as the Champions League group game against Napoli next Tuesday.

There were initial fears that Walcott could be resigned to a lengthy spell on the sidelines following his late-omission from the Stoke clash, however fans will be relieved at the news that the problem wasn't as severe as first thought.

Walcott has been a mainstay in Wenger's side so far this year, and will be looking to resume business as usual as soon as possible in order to keep his positional rivals at bay.
