Antonio Conte: We lost our focus

Antonio Conte's disjointed side struggled from the early stages when captain Gary Cahill was dismissed for a lunging tackle and they found themselves three-nil down at halftime to a team who gained only seven points away from home all last season.

Wales international Sam Vokes scored two of the goals and Stephen Ward the other.

New signing Alvaro Morata from Real Madrid came on to pull one back midway through the second half and then provided an assist for David Luiz, but in-between midfielder Cesc Fabregas was also sent off for a second yellow card.

It was a dispiriting afternoon for Conte, who won the title in his first season at the club but has complained that Chelsea have not signed enough new players while allowing several to leave.

"The sending off of Cahill was a key moment, because to play the rest of the game with 10 and then nine men is not easy," said Conte.

"We tried until the end to reach a good result against Burnley - it was a pity because our fight in the second half was very good.

"After the red card we lost our heads, conceded two goals and then it’s very difficult to change the final result."
