Alvaro Morata has revealed that he is now "very happy" at Chelsea as the Spaniard looks to kick on at Stamford Bridge.
Morata moved to Chelsea from Real Madrid in the summer of 2017 and made a strong start to last season.
The striker's form dipped in the second half of the 2017-18 campaign, however, and his struggles were also apparent in the early stages of this season.
The 26-year-old has scored four times in his last four Premier League appearances, though, with the centre-forward claiming that he is now in a better place mentally.
"In football, physical condition is very important, but the head is the most important thing. If you don't have the head, if the mentality is not good, then you are in trouble," Morata told reporters.
"I had a period where everything – if it is raining, I'm angry because it's raining. If I miss, it's because the pitch is too wet. It was only excuses. It is not good. Everyone can have a bad period in their life, but we are famous, we have a lot of things. Sometimes people think we are not human, with no feelings, with no problems.
"The important thing is to find the right balance. Now, I have, and I am very happy. I'm better. In the last month of last season, I was down, down, down, down. I cannot be more down. When you touch the limit, the only thing you can do is to come back."
Morata has scored 21 times in 63 appearances for Chelsea since arriving from the Bernabeu.
