On Sunday it was clearly evident that both Manchester United and Tottenham have lingering issues that they need to improve upon if they have any chance of securing Champions League qualification for next season.
On Saturday Arsenal ran rampant against a defeated Cardiff team, that did not quite live up to the name of the giant killers that had been bestowed upon them after beating Manchester City earlier in the season.
Manchester City were also dominant in their game against Swansea at the Etihad.
Many believe the German attacking midfielder Mesut Ozil is making the difference to this Arsenal side, but with every game Aaron Ramsey grows in stature.
Ramsey's performance against his previous club was clinical as well as exquisite. He is scoring more goals now, even though he lies much deeper than the likes of Santi Carzola or Jack Wilshere.
He makes clinical runs in to the box, and scores goals that any center-forward would be proud about.
Manchester City for their part are making their home ground a fortress. Joe Hart has been sidelined with his recent dip in form and his replacement Costel Pantilimon isn't making life easier for him either.
The duo of Negredo and Aguero are elevating city to its 2011-12 lethal best. But it was the Frenchman, Nasri, who is flourishing under Manuel Pellegrini. If City can ramp up victories on their away trips as well, they will be title favorites.
A true contrast can be seen in their rivals. Both Manchester United and Tottenham aren't performing well this season, they are eighth and ninth respectively.
They have a lot of catching up to do if they aspire to play in the coveted Champions League come next year.
For United it's their depth in squad that is worrying pundits and fans alike.
There is a distinct inability to finish off games, which was seen against Cardiff City and at White Hart Lane.
Another worrying issue is Robin van Persie's injury. Javier Hernandez and Danny Welbeck are good players but are not comparable to the Dutch striker.
Tottenham on the other hand rely heavily on their midfield players to score goals, the strikers at AVB's disposal are under-achieving, and its a worrying sign for the coach.
Can United and Tottenham catch up to the league leaders? The following weeks are more crucial to these two teams than any other.
