Chelsea must work.

Antonio Conte heaped praise on his side's all round display after they sealed their first Premier League win since August at Hull City on Saturday.

A goal each from Willian and Diego Costa in the space of seven second-half minutes secured a 2-0 win over Mike Phelan's Tigers at the KCOM Stadium and Conte insists his Blues must work harder.

The Italian changed his team's formation to his favourite 3-4-3 following back-to-back league defeats to Liverpool and Arsenal.

However, Conte was impressed with the character of his Chelsea players on the day.

"It's an important win after two defeats," he told a post-match news conference. "This win is important for the team because we are working hard.

"After two defeats it's not easy because you must work and also find the resolution to change and to improve.

"We did a good performance with the right intensity and pressure. I like it when the team plays in this way. I like it so much.

"I saw many of the players with great commitment, attitude and will to change the situation. I am pleased for them.

"We are working very hard and I am sure we can improve a lot if we continue to work in this way."

Chelsea were able to keep a clean sheet for the first time in four attempts across all competitions.

"I am pleased for all the players because we have a clean sheet. In previous games we conceded too many goals," Conte added.

"To finish with a clean sheet is very important. We also scored two and the performance is good. We must follow this with work, work, work!"
