Manchester United endured one of the most surprising and humiliating defeats in their proud history in the Champions League against FC Basel, which knocked them from Europe's elite competition. However, Sir Alex Ferguson has silenced their critics on numerous occasions in the past, and it would be a mistake for anyone to write them off the title challenge. They were back on track with an emphatic victory over Wolves and will hope for Manchester City to drop points in the course of the season.
The Red Devils started the season on a very bright note, especially after the demolition of Arsenal, but they have been inconsistent in the last few weeks. Their biggest concern, as of now, would be the long-term injury to their captain and arguably their best defender, Nemanja Vidic. With Vidic possibly missing the rest of the season, the other defenders need to step up to perform at their best.
The other area which Ferguson could look to strengthen is in central midfield to add some creativity to the team and to fill the void left by the retirement of Paul Scholes. With injuries curtailing the playing time of youngster Tom Cleverley, United could also look for a world class central midfielder in the summer transfer window. Here are 12 players who could make a difference to the side if signed by Manchester United.
