Theo Walcott has been ruled out of the rest of Arsenal’s season and the World Cup in Brazil after rupturing the anterior cruciate ligament of his left knee during Arsenal’s 2-0 win over Spurs in the FA Cup on Saturday.

Arsenal confirmed the forward will be out for at least six months after he was carried off during the second half - and was subsequently pelted with objects thrown from the away end - after appearing to jar his knee when making a tackle .
