Chelsea midfielder John Obi Mikel says things have started well under new manager Andre Villas-Boas.
The 24-year old Nigerian admits the double sessions being held by the Portuguese tactician and his support staff are tough but insists that it will be of great benefit to the Blues as they prepare for the 2011/12 Premier League season.
"The new manager has worked really hard on our sharpness and it is going very well," Mikel told the club's official website.
"The double sessions are hard but working with the ball makes it so much easier than running all the time, and it is enjoyable as well.
"The other coaches are also playing their part in supporting the manager and adding their own ideas.
"Everything so far has been great, we're all enjoying their training and everything is going well so hopefully we can have a good season and for me it will be good to pick up information because I still want to improve."
