Jose Mourinho has said that the referee "killed" Chelsea's pre-season friendly against Werder Bremen earlier today.
Harm Osmers awarded the German side two penalties during their 3-0 win over the Premier League team.
The manager told Sky Sports News: "I learned nothing from this game. Our expectations are not fulfilled because when we decided to have this match here in Bremen we thought about an evolution in difficulty.
"We were expecting a fast game a competitive game but we come here and the referee thought this was a circus for Bremen fans, for them to have fun, and he killed the match
"This game for us would have been perfect. I like the Werder Bremen team, they are fast, intense and they defend with a lot of people. The opponent is perfect for us to compete today but we couldn't play."
The loss was Chelsea's first of the pre-season.
