Despite the threat posed by Manchester City, Alex Ferguson insists he will resist calls for Manchester United to go on a spending spree in the January transfer window. Going into Monday's matches, the defending champion is two points behind City, which has considerably outspent its neighbor in recent years and is now reaping the rewards as it sits at the top at year's end for the first time since 1929. Even though United has debts of around 460 million pounds ($718 million), Ferguson maintains that cash will be made available by the Glazer family, which owns the club. “Contrary to what some people seem to be fixated about, money for a transfer is not a problem if I deem it necessary,” Ferguson said. The 69-year-old Scot delivered the message to fans in the matchday magazine for Monday's game against Wigan just weeks after United's surprise exit from the Champions League in the group stage. “I am perfectly happy with the strength of our squad in terms of depth, quality and age range,” Ferguson said. “I will not be swayed by the endless tweets and blogs urging the club to get busy in the transfer market next month. As far as I am concerned I am marching perfectly in step, true to my beliefs and principles. “While recruiting some of the world's leading players can lift you into contention for honors, it doesn't necessarily take you all the way.” Winger Ashley Young this week joined an extensive injury list that includes center back Nemanja Vidic, midfielders Anderson and Tom Cleverley, and striker Michael Owen. Midfielder Darren Fletcher is also sidelined with a serious bowel disease with no date set for his return. Any further injuries could yet persuade Ferguson to search for additions next month. “Fortunes can fluctuate wildly — that's the football world,” Ferguson said. “If a really top-class player became available, then we would go for him, or if we picked up any further serious injuries, it might be important to add to our squad.” City needs to shed players from its bloated squad — and payroll — in January to help the club comply with UEFA's new financial restrictions, so a repeat of the summer spending that included the 38 million pound (then $62 million) signing of Sergio Aguero is unlikely. With 15 goals already this season, the Argentina striker has quickly established himself as City's most potent force. Only Robin van Persie has scored more than Aguero in the Premier League this season, with the Arsenal striker on 16 goals compared to 13 for the City forward. “Van Persie's an exceptional player, but what is very important for us is that over Christmas we win our games,” manager Arsene Wenger said. Arsenal hosts Wolverhampton Wanderers Tuesday and Queens Park Rangers Saturday. With Arsenal just a point behind and Tottenham two points ahead, Chelsea will be looking to avoid a third consecutive draw Monday when it hosts London neighbor Fulham, which was routed 5-0 by Manchester United Wednesday. Chelsea was held to a 1-1 draw Thursday by Tottenham, which remains above its west London rival in third ahead of Tuesday's match at Norwich. Norwich is well clear of the relegation zone unlike the two other promoted sides — Swansea and QPR, who meet Monday just four and two points clear from danger, respectively. The bottom three is made up of teams from Lancashire. On Monday, bottom-place Blackburn is at Liverpool, 19th-place Bolton hosts Newcastle and Wigan is at Manchester United. Also Monday, Everton goes to Sunderland and Stoke takes on Aston Villa.
