Chelsea's new head coach Mauricio Pochettino is already making an impact at the club.
The Argentine has a huge task on his hands after the club finished in the bottom half of the Premier league table last term.
While Pochettino has a lot of work to do, The Athletic states he is making a positive impression.
The standards of training and gym work are a lot higher at Stamford Bridge as compared to last season.
Interim coach Frank Lampard had suggested the squad was not fit enough towards the end of last term.
Pochettino is also gutting the squad of players he does not want, including the likes of Kai Havertz, Edouard Mendy, Christian Pulisic and Mateo Kovacic.
