SIR ALEX FERGUSON insisted he will not be taking Arsenal lightly on Saturday despite needing just one point to be crowned Premier League champions.<br /><br />Michael Carrick’s winner four minutes from time handed United a hard-fought victory over brave Wigan, meaning Ferguson’s men need just avoid defeat against the Gunners to clinch a record-equalling 18th itle.<br /><br />Want-away striker Carlos Tevez climbed off the bench to cancel out Hugo Rogallega’s earlier strike before Carrick carved open a six-point gap over Liverpool with a cool 18-yard strike to steal victory.<br /><br />But although all bets are off on United sealing a third successive title, Ferguson refuses to take anything for granted against out-of-form Gunners side. “We’ll approach the game the way we always approach a game,” he said. “It is against a very good Arsenal side – I don’t take any notice of what is written, they are a very good side.”<br /><br />Of the Wigan success, Ferguson commented: “We were fantastic in the second half. We kept going, got a little break and we were the better team. A really gutsy performance.”<br /><br />Ferguson opted to restore Wayne Rooney to the attack at the expense of Tevez, plunging the Argentinian’s Old Trafford future into further doubt.<br /><br />But it was Wigan, managed by former United captain Steve Bruce, who showed the more attacking endeavour early on, and they were rewarded on 28 minutes when Rodallega out-muscled Nemanja Vidic before shooting low past Edwin van der Sar.<br /><br />United still ooked the more dangerous, with Rooney twice going close, although they were continually frustrated by the hard-working Latics.<br /><br />Ferguson’s response was to bring on Tevez for Anderson and within four minutes the Argentinian had brought United level with a sublime finish – directing Carrick’s off-target shot past keeper Richard Kingson.<br /><br />With the title in sight, United then went for the jugular and after a period of intense pressure, John O’Shea teed up Carrick to lash home a rising left-foot drive to ensure his side could place one hand on the trophy.
