Chelsea youngster Jeffrey Bruma says they only had themselves to blame for allowing Aston Villa to draw 3-3 on Sunday night.
Bruma was making his first start in the Premier League on the day.
The 19-year-old said: "Everyone knows Premier League games are always fast, quick, strong, so if we don't play our game then they will play their game and you will see that they will dominate us. It can happen.
"At the end, we were dominating them again and then you saw that we scored a goal.
"After, I think we should've kept the ball and been strong in the marking because the guy from Villa had a free header."
The young Dutchman insisted he was not personally responsible for Ciaran Clark's equaliser, adding: "I was marking my man. I think everyone else was, or maybe someone forgot to mark his one."
