Walcott told Saturday‚Äôs Official Arsenal Matchday Programme that his stomach for the battle is second to none.
‚Äú[They were] brilliant - really important goals as well,‚ÄĚ he said.
‚ÄúThe Newcastle win was massive and he showed that desire to get from defence to attack and latch onto things. He‚Äôs an absolute soldier, someone you‚Äôd always want in front of you, a real leader who just wants to win.
‚ÄúTo see him banging in another big goal at Everton was great. I‚Äôm happy for him - he had his injury problems last season but he‚Äôs one of the best defenders in the world without a doubt.‚ÄĚ
