The Chelsea boss heaped praise on the 36-year-old when speaking at his press conference ahead of his side’s game at home to Sunderland on Sunday afternoon.
“One of my best players ever, one of my best professionals ever, a Chelsea legend and a legend in the Premier League,” Mourinho said.
“I have to honour him and wish him all the best in the States. He is a big loss for English football.”
Lampard played under Mourinho between 2004 and 2007 in a period where Chelsea lifted two Premier League titles, two League Cups and an FA Cup.
Mourinho returned to Chelsea in 2013 before allowing Lampard to leave for Manchester City last summer where he’s made 34 appearances in all competitions, contributing seven goals and one assist.
The ex-England international’s last game in England will be against Southampton at the Etihad on Sunday afternoon with City having already secured a second-place finish in the table. He will have a summer break before joining up with his New York City teammates in July.
