Rosenior has inherited a young squad, but one that has plenty of experience behind it at domestic and international level. He pointed out that it is not always beneficial for leaders to be overly animated and noisy, and the way the likes of Reece James and Moises Caicedo lead by example can be more impactful.

‘I'm very happy with the leadership in my group,’ said Rosenior.

‘I have played with players who are very loud, who shout and point and actually don't lead because they hide from the ball and don't take responsibility. I won't name names, but there's different ways to lead.

‘Our generation – my generation – is different to the younger generation in terms of communication, but I love the group - whether it's Reece or Enzo [Fernandez] or Moi or Trevoh Chalobah or Tosin - they're all leaders in their own right.

‘And they have to be themselves. I'm not going to ask them to be something that they're not. A good leader in modern football is someone who’s authentic and honest, trustworthy and true to themselves.’

It is now over two weeks since Rosenior stepped through the door at Stamford Bridge, and in that time he says he has learned plenty of lessons. He detailed some of them at his press conference today.

‘Loads in terms of individual performances, and in terms of the improvements that I've asked for. It's been really positive signs. Our counter-pressing and our energy levels and our intensity have been very good in the last few games. That needs to continue.

‘So yeah, there's loads of lessons for me and my staff to learn, and there's probably a lot more to come as well.’
