Former Manchester United manager Jose Mourinho has heaped praise on Frank Lampard but has concerns on how his Chelsea side will perform against 'big teams'.
The Blues youngsters have been a revelation this season with Tammy Abraham sitting second on the top scorer's list with 10 goals, just one below Jamie Vardy.
Speaking as a pundit on Sky Sports, Mourinho lauded Lampard as he revealed his concern with Chelsea, "In the first weekend I was worried and I’m still worried with the big matches. I think fantastic work. The kids coming into the team are fitting amazingly well with the top class players like Willian and Kante.
"I think really, really great work by Frank. But, they lost twice against United, they lost against Liverpool at home. They conceded four goals against Ajax and I’m very, very curious to see Chelsea in the next match at the Etihad."
