This coming season is one of the most anticipated seasons in a long time.
Arsenal have strengthened well, Manchester United have a new manager in Louis van Gaal, Liverpool have sold key player Luis Suarez, Manchester City are defending their title and Chelsea are spending big.
All of the top four have strengthened and it looks like any of them are capable of winning the Premier League title, but for Jose Mourinho this season is vital.
Last season Mourinho claimed that Arsene Wenger was a "specialist in failure" and then The Gunners went on to win the FA Cup and Chelsea won nothing.
But this season the Chelsea boss needs to win the league in order for him to keep his job.
No more mind games
Mourinho uses mind games as a major part in his management as was seen when he brandished his striker Samuel Eto'o as "old" and then saw him score a hat-trick against Manchester United.
This season, however, he cannot rely on the mind games to win the league because of the confidence all of his rival managers now have. Chelsea need to install a philosophy to their game.
Last season fans saw Chelsea park the bus on more than one occasion while against Arsenal they executed a perfect counter-attacking display.
Throughout the whole of last season Chelsea never had a consistent way of playing. This is the season to establish themselves with a trademark style as their new signings Diego Costa and Cesc Fabregas give them new dimensions to their already illustrious squad.
