I think we've seen a taste of it in how he reacted after being properly beaten by PSG and following it up with a convincing win against Chelsea and a commendable point against Liverpool all against the backdrop of major injuries. Even that he brought a rag tag team to Paris and convinced them the tie was still there for the taking is testament to his managerial abilities. Yesterday was disappointing of course but we were definitely not shown up as unable to compete at that level, just didn't get the rub of the green. Unfortunately, given the handicap start to his managerial career there is no room for error so even when we remain unbeaten in the league in over 2 months, this loss away to Arsenal feels hugely disappointing. I hope the dressing room isn't feeling it the same way as fans do.
