Tottenham boss Mauricio Pochettino could only take a few lessons away from the Etihad on Saturday after his side were beaten 4-1 by the Premier League leaders Man City.
The Argentinian says he will use the experience to gauge where his own team is currently at compared to a team he admits are simply running away from the rest at the moment.
The Spurs boss felt his side started the game well, despite the end result, and speaking to the press after the game, via the Express, he said: "We have a lot of positive things, because we played a team in very good form with very good momentum.
"It wasn't bad at the start, but the way we conceded from a corner was a big mistake and a massive present for them, when you play a team in very good form, you cannot give away these gifts.
"When you're playing a team with good quality, if we take risks, we give them the possibility of making chances.
"We tried to play, but they were better, we have to congratulate them. So far, they are the best team in England.
"I am very disappointed. We must learn, because one day we want to be in a position to win the Premier League, but today was a big lesson for us.
"We were never going to come here and play a different way to how we normally play, so, we tried, we tried to force the opener, but they were better."
