Alvaro Morata opens up on his Chelsea struggles: 'I only wanted to stay at home'
• After a bright start to life at Stamford Bridge, Morata's goals have dried up
• The Spaniard reveals how he managed to navigate through the dark times
Speaking to the Mirror, the 25-year-old said: "I had a block in my head and I didn't want to speak with anyone. I didn't want to listen to anyone. I only wanted to stay at home.
"Probably it's not depression, but it's similar. In football it's all about the head and in the last year I suffered in this aspect because I came here with a lot of expectation, a lot of pressure.
"I began well, but after I had these things. I had pain in the back. I don't know why. I did a lot of things to try to recover but I couldn't and I didn't know why. It was hurting in my head.
"Today, in 2018, if you don't have 100 per cent power, you are in trouble. You have the best strikers in this league and if you come here as the most expensive player you need to be 100 per cent."
