The new Blues striker who signed from Real Madrid played for 15 minutes in the Community Shield against Arsenal last weekend before missing a penalty in the shootout.
And Morata realises what is ahead of him after being criticised heavily following Chelsea’s defeat at Wembley.
He said to Marca: “I admit it’s a very important amount, but I have personality to play quietly and go my way.
“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.”
Morata is battling with Michy Batshuayi for a starting spot in Chelsea’s Premier League opener against Burnley tomorrow.
The Spaniard was linked with a move to Manchester United before Jose Mourinho opted to sign Romelu Lukaku from Everton instead.
And that led to Morata joining forces with Antonio Conte at Stamford Bridge.
