Alex Oxlade-Chamberlain thinks Theo Walcott has proven beyond any doubt that he is capable of taking on the role of Arsenal's assassin for the rest of the season.

Arsene Wenger had seemed unsure whether Walcott could function effectively as a striker but that theory has been blown out of the water over the festive period after the England international starred in all three games he started up front.

"He definitely has all the attributes to play up front," said Oxlade-Chamberlain of Walcott, who now has 14 goals for the Gunners this term.
