PSG goalkeeper Marcin Bulka admits Alvaro Morata struggled with the 'hatred' of Chelsea's fans during his time in London.
Morata left Chelsea last year for Atletico Madrid, with Bulka following him in the summer for Paris.
The young Pole told Foot Truck: "He had a bad time at Chelsea. The hatred of the fans affected him and it showed even in training. It was easy to stop his shots, he had a mental block. Sometimes he was even vindictive. When he gets angry, he shoots as if he wanted to kill the goalkeeper."
Bulka also revealed an anecdote Morata told him when training with Iker Casillas at Real Madrid.
"Once his shot took off Iker's cap and he started laughing. He told me that after training, Casillas approached him, hit him in the face and said: 'You can score a goal, but don't make fun of me'."
