Chelsea's players can expect big changes under new gaffer Luiz Felipe Scolari.
It will be in stark contrast to predecessor Avram Grant who was happy to let assistant Steve Clarke run the sessions.
World Cup winner Scolari also wants to inject more style into Chelsea and will insist his players work with a ball at their feet at all times.
He said: "I prefer to win with style."
Scolari expects every squad member to have a precise role in the team and will demand they practise flat out until it is second nature.
A Chelsea insider said: "Scolari has very defined ideas. The players will have to work hard."
