Thomas Tuchel is only four days into his new job but the manager is already putting his stamp on Chelsea training.
Tuchel was appointed following the sacking of Frank Lampard this week and took charge of his first game on Wednesday - a 0-0 draw at home to Wolves.
The 47-year-old is looking to implement his ideas quickly and could be seen putting his methods into practice at Cobham on Friday.
In one part of the session, players used a tiny football - a tactic often employed to improve ball control.
Smaller goals were also in use when the team moved back to playing with a regular football.
Tuchel has developed a reputation for his innovative training methods during his coaching career.
While manager of Borussia Dortmund, Tuchel is said to have made defenders hold tennis balls to stop shirt pulling and shaped pitches into diamonds to encourage diagonal runs from his forwards.
The German is hoping to get his first win as Chelsea boss this weekend with his side facing an in-form Burnley at Stamford Bridge.
Sean Dyche's men, who have won their last three games in all competitions, are known for their physicality and strength from set pieces.
Chelsea goalkeeper Edouard Mendy looked to be getting a taste of what to expect with Petr Cech putting the shot-stopper through his paces.
Cech held a rucking shield against the goalkeeper while he jumped to catch crosses, mimicking the physical challenges he is likely to receive from Burnley's forward's and defenders.
Tuchel admitted this week that he believes it's not realistic to push for the Premier League this season but insisted he is at Chelsea to win trophies.
'I am in a club who's DNA it is to win and go for trophies. I am here to challenge for every trophy that we play for and it means realistically that this year it is about the Champions League and FA Cup.
'To speak about the Premier League title is not realistic because there are too many teams between us.
'We will just lose focus if we start here but our job is also about relationships with the club and team, to push everyone to the limit.'
