Goodison has traditionally been a difficult place to go for Chelsea and today's game was a return to form after last season's 6-3 drubbing.

Everton were better than Chelsea. Much better. Their superiority was perhaps best embodied by Steven Naismith, who only entered the game as an 8th minute substitute, and yet seemed much sharper and hungrier than the defending Champions.

Mourinho must now wonder what to do with a team under performing in such spectacular fashion. Their triumph last season was built on consistency but it would seem negligent not to make changes now. Ivanovic looked weak, Fabregas lacking in ideas (and confidence) and Hazard far from the marauding winger who ghosted past players for fun last term.

There are big questions to be answered and here are the big things we learned ...

Ivanovic in permanent decline

You can't argue with the numbers. Even the most optimistic Chelsea fan must have their serious doubts about the Serb at this stage. Perhaps it's time for a return of Azpilicueta to right-back?

Naismith big game player

Naismith only came into this game as an early substitute for the injured Besic. Was he ready? You bet. The Scot got a hat-trick to make it his 5th in three games against Chelsea and seems to relish the big games. Can he deliver on a more regular basis, though, remains to be seen.

Chelsea's fear factor gone

Team's used to fear Chelsea. Heck, only 6 months ago virtually every game involving Mourinho's men was described as a 'banker'. However, a tepid end to last season combined with a, now, disastrous start to this campaign has left that fear factor well and truly shattered.
