6) The players need to step up
The most important thing that will help Chelsea improve next season would be the players stepping up. Most of this campaign, it felt like the players were still in pre-season with no motivation to work hard. They were too casual for the most part and were over confident.
Some might even argue that Mourinho lost his job only because his players failed to step up. Fabregas was quoted saying that the Portuguese trusted his players too much and were given too many holidays. He even said that it was the players that let the former manager down.
It is clear indication that the players need to start performing again to avoid another mishap of this magnitude. With this campaign coming to a close, the Chelsea stars need to look up to next season and give their all if they are to make the Blues great again.
