“I have to be honest and say that it was a good week of work for us,” he said.
“And I also think that mentally it’s very important, the happiness of results, than one or two more days to rest, and I think the fact that Man City qualified for one final compensates for everything.
“Apart from that, I think they have 20 players the same quality. For me to play (Kyle) Walker or Cancelo, to play (Nicolas) Otamendi or (Aymeric) Laporte, to play (Sergio) Aguero or (Gabriel) Jesus, to play Bernardo Silva or David Silva.
“This is the kind of squad that I think they could play four matches a week and the quality would be the same.”
