Antonio Conte took the blame for Chelsea's failure to protect their lead in a thrilling 3-3 draw against Roma in the Champions League.

Blues boss Conte opted to deploy Brazil defender David Luiz in midfield in a bid to solidify his injury-hit team.

Luiz gave Chelsea the lead at Stamford Bridge on Wednesday, but although Eden Hazard doubled the hosts' advantage before halftime, Roma hit back impressively.

Aleksandar Kolarov's deflected strike reduced the deficit before Edin Dzeko netted with a brilliant volley and then a glancing header to put Roma ahead.

It took a late Hazard equaliser to stop Chelsea suffering a third successive defeat in all competitions, and Conte admitted his tactical switch had backfired.

"I didn't like the type of football we did for a lot of the game, but it's right to take the responsibility for this," Conte said.

"I tried on one hand to protect my team, to become more solid and to move our central defender into midfield. On the other hand we lost totally our style of football.
