Chelsea stars warned they must get nastier ahead of FA Cup clash vs Nottingham Forest

“The results would maybe point towards this period being Frank’s first major test as a manager – but we have had moments when we have been winning games where we have been just as frustrated.

“Frank is one of those who lives and breathes it. At night you might get a text message saying ‘look at this, look at that.’ He is passionate about improving players, passionate about winning.

“There were times at Derby last season when we were winning but certain things were not being carried out we were asking for. He is a deep thinker. He was like that as a player and he is like that as a manager.”

Forest manager Sabri Lamouchi has saluted the courage Lampard is showing, saying talk of his inexperience is ‘stupid.’

The former Inter Milan midfielder said: “Talk about Frank being too young for a job like that is stupid.
