Era under Villas Boas: "Chelsea" defeats "Birmingham" in the FA Cup (VIDEO) © EuroFootball.com

Roberto Di Matteo started his time at London's Chelsea with a win: goals from Juan Mata and Raul Meireles secured the team's victory against Birmingham.

The capital team advanced to the sixth stage of the FA Cup only after a replay, as they couldn't defeat Birmingham's eleven at home.

This time, the performance was enough for the second tier league club to fall against one of the tournament favorites. A few days after firing coach Andre Villas Boas, Chelsea was not hindered by Juan Mata missing a penalty kick.
