‘We were doing some different things in training to create overloads and I saw it done in abundance today.
‘The team just has so much flexibility and I can do so many different things with them because they are intelligent and they know how to win games with the same relentlessness that I demand.
‘We’re used to being in this position, however, everybody knows the type of games we’ve got coming up.

‘The team was incredible today. It wasn’t just about having fun, we were so clinical and so ruthless. But you see the difference with our squad depth now; with so many players back it’s driving the standards at training and that’s where the magic happens.’
