City are now just two wins away from being crowned Premier League champions, and even though his side were losers on the night, Lambert can appreciate Pep Guardiola's high fliers.
"They are as good a team as I have seen in a long time," the Stoke boss told Sky Sports News. "I think with their movement, trying to keep them at bay [was hard].
"I think the way they play the game is terrific, the passing, the movement, you don't really see it until you get close to it, it's a very difficult game to stop. This is a really really top side we have come up against."
Stoke currently reside second from bottom in the league table, one point from safety.
