"He has had a long summer but I will factor in a break for him at some point because it's important."
Di Matteo conceded that the Blues were still behind Manchester City and United, but hopes that with several new recruits to the team, this season will bring better fortunes for the Stamford Bridge club.
He added: "We have to try and catch up with the Manchester teams. The gap last season was big so our aim is to catch them up.
"All the players are looking forward to finally starting. Our aspiration is to do better than last season in the Premier League."
