Lampard said he was very satisfied with his team's performance when they beat Barcelona in a pre-season match at Saitama Stadium 2002, Saitama, Japan, on Tuesday.
Tammy Abraham and Ross Barkley were the winners of the West London team. Barcelona's goal was recorded by Ivan Rakitic in injury time.
"I am very happy. It is really good on and off the pitch. Especially today, I see there are many very signs of what we have done, which is very good. There is a lot to improve, but this is a good trip," LAmpard said on the official Chelsea website.
"What I have learned about the players he is is a good group that is strong. They have done everything I asked them and more. So, they deserve a few days off," he added.
