Manchester United boss Jose Mourinho is happy to face Frank Lampard's Derby County in the Carabao Cup.
The pair enjoyed high moments in their career together at Chelsea.
Mourinho told MUTV: “I don't think it's strange, it's nice. My first generation of players at Porto and Chelsea have finished their careers and many of them have become managers.
"Frank is the first that I'm going to play against and it's not strange at all. He always wanted to be a manager. I think his objective is to win a top-two position in the Championship to be promoted, but of course we had Derby County last season in the FA Cup at Old Trafford and every team from the Championship that visits a Premier League team is always a special motivation for them."
