Alvaro Morata has told Marca that he has "the personality" to live up to being Chelsea's club-record signing and answer the critics who he says "are already killing me" by scoring "more than 20 goals."
Chelsea lost 4-1 on penalties after a 1-1 draw with Arsenal in the Community Shield at Wembley, with Morata replacing Michy Batshuayi in the 74th minute and failing to make a significant impact before missing his spot kick in the shootout.
It was an inauspicious start for a striker the Premier League champions paid an initial fee of £58 million to acquire from Real Madrid this summer, but Morata is adamant that it will not deter him.
"I admit it's a very important amount but I have the personality to play with calmness and continue my path," the 24-year-old said. "I have only played two preseason games, 15 official minutes and a missed penalty. They [the critics] are already killing me so I know what awaits me.
"It's the price you have to pay for such a big transfer. It's something that motivates me and makes me work harder every day, to be an extra hour each day in the training ground. I know that double the people are watching me now."
The move also gives Morata a long-awaited chance to work with Antonio Conte, the coach who brought him to Juventus before resigning in the summer of 2014, and the striker has set himself a target of 20 goals in his first season at Stamford Bridge.
"Now I have to adapt to the new team, to an Italian coach who is very tactical, there are many changes," he added. "But now I have adapted and I'm looking forward to playing. I hope that is reflected on the pitch.
"I have to adapt to the team system, which is like an Italian one because of the coach. I need to understand Conte well, he demands the opposite to what my past coaches asked of me. I will play in different positions, with diverse tactical plays.
"I've understood those changes already and from now on, everything should be easier. I don't think I have to adapt to the Premier League but rather to my new coach. Antonio is not only asking me to make the usual moves of a striker.
"I hope I can score more than 20 goals. That is my job. But I'm not obsessed in that sense as I would change it for any collective title.
"During my time at Juve I didn't score more than 20 goals a year but I won every title except the Champions League. I've scored 15 or 16 goals and I've lifted titles and other strikers have scored 35 and haven't won anything."
