Frank Lampard has defied expectations in his debut campaign at Chelsea. Despite operating under a transfer ban and in his first season managing in the top flight, the Blues legend has guided his men to joint-second so far. What's particularly impressive is that he's also broken away from some of the club's more negative traditions. Young players like Tammy Abraham and Mason Mount are no longer being shipped out on loan - partly because of the transfer ban, of course - and are getting their chance in the first team.It's paid dividends too, as the striker is currently the Premier League's second highest scorer and netted his first England goal in midweek. On top of that, Chelsea are playing attractive football. The only real cause for concern is their defence. Jose Mourinho summed it up on Sky Sports when he appeared as a pundit on November 10. "After the first weekend [a 4-0 defeat to Manchester United] I was worried. And I'm still worried with the big matches. 

"Fantastic work, the kids that are coming into the team are fitting amazingly well with top-class players like Willian, [N'Golo] 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. 

"I'm curious to see if they found that great empathy between the good football they play and the pragmatism that the top teams must have, especially to play against the top teams. When they find that, I think they have a great team for the future. 

"I don't believe they are going to finish top two, but I believe very seriously they are going to finish top four." 

Mourinho's comments were actually quite balanced and fair. 

Nonetheless, they seem to have got under the skin of Lampard's assistant, Jody Morris, who took to social media with two posts that have landed him in hot water with the club. 

In response to the comments, he posted on Twitter: "Jose is still worried."

At the time of writing, he hasn't taken the tweet down.

He also shared a video on Instagram in which he pretended to cry, while 'Bittersweet Symphony' played in the background. 

According to the Daily Mail, Chelsea insiders feel his social media activity is "unbecoming and inappropriate" for such a senior figure in the coaching set-up. 

Morris has therefore been asked to show more restraint in future. 

It's understandable that Chelsea are embarrassed by their coaches mocking a former manager - and at any rate, Lampard and his backroom staff would probably do well to listen to Mourinho's advice.
