Not to pile on, but the last 5-10 years have also been some of the change-iest in the Premier League's history, with the influx of oil money bringing Chelsea and City to the top and making things overall more competitive. It's ok though, Tracer just started watching 6 months ago.
Chelsea looked GOOD in the first half today, then slightly Mourinho-ish and depressing in the second (still good though). I think this is the year they really start making their presence felt again after a few years of rebuilding. Kind of too early to get a read on teams at this point though, especially those like Arsenal and Liverpool who have had a lot of personnel changes.
