Chelsea boss Carlo Ancelotti admits Jeffrey Bruma struggled to cope at times during yesterday's 3-3 draw with Aston Villa.
The 19 year-old played at centre-half for his first Premier League start.
"Defensively we lost something," he admitted. "Obviously i just want to say that Bruma played very well but we are without Alex and Ivanovic, we lost some energy on the high ball.
"We conceded the second goal for this reason, the third was different because we needed to have more attention in the box."
