"Benni had a great first season. He quickly settled into the English game," Mourinho told the Sun.
"He is the kind of striker every coach wants and I am no exception.
"I've worked with him successfully in the past at Porto. I do like Benni.
"I'm not surprised about his achievements. He could score goals anywhere.
"If he stays injury free, he'll surpass his achievement of last season.
"I saw the possibility of us reuniting at Chelsea but he has a contract.
"I could tell that he wanted to play for me again because we had a wonderful time together.
"But Blackburn said he was not for sale and you have to respect that."
