“We wanted to win but it a tough game to navigate.
” I asked the lads to be professional and get their attitude right and they all certainly did that.”

The former Derby County manager also expressed his pleasure over the performance of every other players.
“Everyone was pretty good. Kai Havertz did some really nice things.
” I asked him to play on the wing today, even though we’ve seen him more centrally recently but he can do different roles for us, which will be important.
“Kovacic again showed his qualities, Rudiger was solid at the back, Azpilicueta professional.
” I liked the discipline of the team.
“You’ve got to respect the opponent and they had a few little counter-attack moments but nothing great themselves.
” Maybe there was a bit of zip taken out of our performance in a way but I’m relatively happy.’
