Antonio Conte took responsibility for Chelsea’s below-par performance in the 3-3 draw with Roma.
The home side looked in control of the Champions League clash after first-half goals from David Luiz and Eden Hazard put them 2-0 up at Stamford Bridge.
Blues boss Conte, who deployed Luiz in midfield, admitted that his changes had a negative effect.
“I like to be honest and for sure I didn’t like the type of football we played for a lot of the game,” he said.
“I tried to protect my team and move my defenders into midfield but we lost our style of football. I didn’t like this.
“We were 2-0 up but not in control of the game. I think the result was fair. We know Roma are a strong team but we gave away too much possession.
“I have to praise my players. They showed me a big effort and commitment, otherwise we would have lost this game.”
The result nevertheless keeps Chelsea top of Group C – two points clear of Roma and five clear of Atletico Madrid, who were held to a goalless draw by Qarabag.
