Chelsea striker Alvaro Morata has said that he's ready to prove doubters wrong and feels motivated for the Premier League to start.

In an interview with Spanish outlet Marca, the forward revealed that he had already noted the intense interest in him after his big money summer move.

The Spain international said he was aware of the pressure surrounding him due to his £70.6m price-tag and was motivated to prove the critics wrong who are 'killing him'following his miss in the penalty shootout defeat against Arsenal at the Community Sheild.

The striker managed 15 minutes from the bench near the end of the game, followed by a miss from the penalty spot as Arsenal ran out winners and Morata was criticised in some quarters.

"I admit it's a very important amount (the fee) but I have personality to play quietly and go my way,"Morata told Marca, as reported by the Metro.

"I have only two pre-season games, 15 official minutes and a failed penalty (in the Community Shield's loss to Arsenal) ... and they're already killing me, so I know what's ahead.

"It is the price that must be paid for such a large transfer. And it's something that motivates me and makes me work harder every day, to spend an hour every day in the Sports City training. I know now twice as many people look at me".

The striker swapped Real Madrid for the Stamford Bridge side after a summer of interest in him, with Manchester United also pursuing a deal for the Spain international.

But it was Chelsea that met his considerable asking price, bringing him in as a potential replacement for his national team teammate Diego Costa.

Morata has also laid down a goal target for himself ahead of the new Premier League season, as reported by the Dailymail.

He added: "I want to score more than 20. It's my job. But it is not an obsession for me ahead of winning titles for the team. For example, when I was with Juventus I did not score more than 20 goals.

He also revealed that interest from Antonio Conte helped him decide to move to Chelsea

"I knew Conte loved me," he revealed.

"I had talked to him many times. In a way, I felt indebted to him because I signed for Juventus and he had to go.
