Arsene Wenger‚Äôs side were forced to dig deep for the three points following Carl Jenkinson‚Äôs red card, and Walcott was delighted they showed their battling qualities.
‚ÄúIt was an important win,‚ÄĚ the England international told arsenal.com. ‚ÄúThe three points have us on a high and we‚Äôve got a nice week now without any midweek game.
‚ÄúA lot of players are back from international duty and need a bit of a break. Some may be rested for the FA Cup game, but that‚Äôs just as important as we want to go far in that competition. If we lost [at Sunderland], we would have been dwelling on it for so long, so I‚Äôm glad we didn‚Äôt.
‚ÄúWe‚Äôre very confident [of finishing in the top four]. We can battle through any sort of situation. The teams around us are winning as well, but we‚Äôve just got to make sure we look after ourselves and try to win as often as we can.
‚ÄúWe‚Äôll see where we are at the end of the season but we‚Äôve got to show the belief we did at Sunderland. I felt there were a lot of winners in that dressing room and the boys were fantastic.‚ÄĚ
