The start of a new era for the Premiership?

This years title race is for me, going to be one of the most exciting ones ive ever seen. With the big boys slipping up, it gives chance to teams who have previously been hovering on the fringe of Champions league football like Tottenham and Aston Villa to really make inrodes into the top four.
So far this season weve already seen the likes of Arsenal, Man Utd and Chelsea slip up more than once, most recently Chelsea against Manchester City and with the African Nations coming up in January, its going to make the race for top spot even more exciting. With Chelsea losing Didier Drogba, Jon Obi Mikel, Michael Essien and Salomon Kalou, its going to be interesting to see how the Blue's cope with these losses.
With the money thats involved with football now, notably Manchester City, its going to be intriguing to see how the likes of Liverpool and Arsenal plan to match the ambitions of the likes of City in the transfer market. Will we see the likes of these clubs fall into mid table teams? To me, it seems inevitable that City, Tottenham and Villa will push the current top four all the way.
Weve already seem Liverpool struggling this season, all be it they've been hit with injuries to key players.
I feel the next few seasons will make fascinating viewing for all involved and with the standard of football only going to get better in my opinion, will we see a new 'top four' in the not so distant future?
