Morata, 24, hit a hat trick at the bet365 Stadium to take his Premier League tally to six goals in as many matches.

The £58 million striker was happy to prove his ability after the exit of Diego Costa to Atletico Madrid, and thanked Chelsea supporters after they changed the words to a controversial chant about him.

"It's football. Sometimes the ball doesn't [go in], like against Arsenal, and today, we had two chances and made two goals," he told the club website of Chelsea's first-half display.

"We sent a good message to all the Premier League. Chelsea is in the fight for the title and it's the thing that we want.

"The most important thing is we won today. It's a difficult place to come, but we won and now we can look ahead to the Champions League."
