Theo Walcott has been ruled out for at least another fortnight after suffering a setback on his recovery from abdominal surgery. It means that he will miss the Champions League match against Borussia Dortmund on Tuesday the Premier League fixture with Crystal Palace and the Capital One Cup game against Chelsea. He then has a small chance of being fit to face Liverpool on Nov 2 although the match against Manchester United on Nov 10 might now be a more realistic target. That would put Walcott in contention for involvement in England’s Wembley friendlies against Chile and Germany on Nov 15 and Nov 19. Although Arsenal manager Arsène Wenger would prefer his player eased himself back gently after undergoing surgery Walcott now faces competition from Andros Townsend for his place in the national team and with England not playing again until March and a World Cup on the horizon he will be keen to feature. Walcott had returned to training last week but suffered the setback while running on Thursday. “He had to stop to jog again – he is at least two weeks away now” Wenger said. The Arsenal manager is also waiting on a doctor’s assessment of Mathieu Flamini to know if he is available on Tuesday after he was forced off with concussion and blurred vision following a clash of heads with Alexander Tettey. “After I got the bang on the head it was very hard for me to just speak and to know where I was” Tettey said.
