The Portuguese boss wanted Lampard to follow him to Inter Milan when his first spell as manager at Chelsea ended in September 2007.
“I tried to take him to Inter, but I was saying, ‘You belong to Chelsea and you should stay’,” said Mourinho.
“I wanted to bring him but I also wanted him to stay. I told him, ‘If you want to come I want you’, but in the end he did what he wanted to do and signed a new contract at Chelsea.
“He was not very far away, but in the end I was happy and I told him so. It was a good decision.”
