If Manchester United's recent victory sent any message to their domestic title rivals, it's that they have got an equally strong and interchangeable team that is yet to hit its peak. United created masses of chances, played elegantly with pace, skill, and conviction and above all showed their title contenders that they are still very capable of throwing a spanner in the works at Stamford Bridge this season.
As convincing and dominating as United where they also demonstrated that they have a squad as strong as Chelsea's if not better attacking wise. Influential players like Scholes and Rooney came off along with Rafael DaSilva, and were replaced with players just as capable of creating opportunities for the front men.
An interchangeable squad and a wealth of options in most positions is exaclty what is needed to challenge for the title realistically and despite United's slow start, they have proved they have it in abundance.
Dimitar Berbatov has also gone a long way to silencing the critics who were claiming he hadn't exactly set the world alight since his £30 million move to the Mancunian club. His link up play with the attacking players was breathtaking to watch and he proved he can be just as important for his team as the season progresses.
Chelsea have a chance tonight to send just as much of a message back to Old Trafford when they play in the Champions League, as I'm sure Sir Alex Ferguson will be interested in the result and the effect it has on their title ambitions. So far this season Chelsea haven't shown fully that they have a catalogue of higher quality performances they are yet to delve into. Man Utd however have shown that they are just heating up.
If the Chelsea faithful thought that their displays in the EPL so far where enough to comfortably romp to the title this season, Manchester United's recent performance albeit against a low par team has gone a long way to show that Chelsea have considerably more to worry about than initially anticipated.
