A year ago, ESPN FC's correspondents each selected their club's 15 most important players and just 12 months on, there's been a huge amount of changes.
Mohamed Salah's rise has made him Liverpool's main man while it's a new era at Arsenal with Unai Emery looking to Pierre-Emerick Aubameyang to score the goals in his first season at the club.
Kevin De Bruyne's influence has grown even further at Manchester City and it's all change at Chelsea too, with Jorginho set to be integral to how Maurizio Sarri wants to play.
ESPN FC's club correspondents run the rule over their team and select the 15 most important players, with a key for if they've risen, fallen, stayed the same or become a new entry.

Manchester City: Kevin De Bruyne has become Pep Guardiola's key man, while Vincent Kompany is a big faller.
Manchester United: If Jose Mourinho wants to catch Manchester City, he'll need Alexis Sanchez on top form.
Tottenham: Harry Kane is still the main man at Tottenham but Davinson Sanchez has become increasingly crucial.
Liverpool: Of course it's Mohamed Salah -- but in a new-look Liverpool, there's plenty of change from last season's top performers.
Chelsea: Jorginho has stormed to No.1, the key component in Maurizio Sarri's system, while David Luiz has also bounced back.
Arsenal: A year on from when Sanchez and Mesut Ozil were Arsenal's most important, it's all change with Pierre-Emerick Aubameyang leading the way.
