Chelsea's new goalkeeper Asmir Begovic has described training as a "step up" following his move from Stoke City.
The 28-year-old officially joined the Premier League champions last week for an £8m fee.
Begovic will have to fight for his place as he attempts to dislodge Thibaut Courtois from the number one spot, but the Bosnian international is relishing the challenge.
"The experience has been fantastic," Begovic told the club's official website. "Great to be part of this group of guys and this team and they have all been really welcoming which I have enjoyed.
"Everyone from the coaching staff has been brilliant and the training has been great, so it is definitely a step up and the level is really high here. It is very demanding and I am loving the challenge and it is good to be a part of it."
Chelsea will begin their domestic season at home against Swansea City on August 8.
