Everton managed to pull off arguably the biggest Premier League surprise of the weekend on Saturday, as they overcame Chelsea at Goodison Park, via a Stephen Naismith goal. 

It is notoriously difficult to emerge from Goodison Park with three points. That said, a trip to Everton represents exactly the kind of game Chelsea teams thrived upon in former years under the stewardship of self-professed 'Special One' Jose Mourinho. Particularly during the title winning seasons of 2004/05 and 2005/06, Chelsea defeats became something of a collectors item.

This season's Chelsea side is a different proposition. The west Londoners have won just one Premier League title since 2006, even finishing outside the top four in their Champions League winning season of 2011/12. There are high hopes that Mourinho can bring further glory to Stamford Bridge, although their start to the season has been underwhelming.

During their 0-0 draw with Manchester United and their defeat at Everton, Chelsea lacked a killer instinct. Throughout both games they had a host of chances, particularly against Everton, yet failed to find the net on both occasions. 

Jose Mourinho was particularly vocal in his pursuit of England striker Wayne Rooney throughout the summer transfer window. David Moyes was criticised for Manchester United's summer transfer business after very few arrivals. However, the Scot deserves great credit for retaining Rooney's services in the face of Chelsea's interest.

The purchase of Samuel Eto'o appeared to signal the end of Chelsea's interest in Rooney. At the age of 32 Eto'o appears to be past his prime, and is surely a stopgap signing to keep Chelsea ticking over until further transfer windows.

The Cameroon international was a fantastic player for Barcelona and Inter Milan. If he can reproduce anywhere near the same level of performance for Chelsea he could prove to be an inspired signing. Although he is short of match fitness, his debut on Saturday showed little to suggest that he will be able to hit those heights.

The failure to land Rooney makes Mourinho's decision to allow Romelu Lukaku to leave for Everton on loan look like a strange one. The Belgian provides a more direct option to Eto'o or Torres, and his 14 Premier League goals for West Bromwich Albion last year show he has the talent. 

Rooney looks to be playing some of his best football in a long time for Manchester United. He managed to create two goals in just over half an hour on the opening day against Swansea, and looked sharp as he got his name on the score sheet against Crystal Palace. The creativity and power that Rooney provides would surely have strengthened Chelsea's squad significantly.

Chelsea do possess a host of attacking talent in players such as Oscar, Mata, Hazard and Schurrle, and in Jose Mourinho they have a man who is genuinely passionate about the club, and has a proven track record of getting the best out of his teams.

The Blues can consider themselves as one of the favourites to clinch the Premier League title in the beginning of the post Sir Alex Ferguson era. You just feel that the acquisition of a world class striker in his prime would have tipped the balance well and truly in their favour.
