Chelsea will be watching their Premier League rivals Liverpool extremely closely in the coming weeks and months as both sides look to make an immediate jump back into the Champions League. The two sides that finished second and third last year have had the biggest drop-off of any team in the league this season.
Part of Liverpool's massive difference is genuine overperformance and above-par, unsustainable excellence last year, that said, their tally of 67 points would only have been enough to scrape into the top four on three occasions since 2015.
Chelsea, on the other hand, have spent more than every other team worldwide but have had the worst pound-for-pound season in league history. Their drop is less to do with unsustainable excellence and more short-term mismanagement mixed with long-term planning neglect.
