Guardiola said: "We started really well but they are incredible team. We had our moments, they had theirs. The way they play it is not easy. We take that point.
"First half we had momentum, lots of chances first half. And after we gave away the penalty, we suffered. It was a good game for the spectators."
On De Bruyne being annoyed, he said: "That's good. Have a chance next game to prove it. We need a player who keeps the ball. Its not about pressing. Kovacic is really good at that. We were happy with Kevin. It's not a problem. We're fine.
"I know how difficult it is at Anfield. It is difficult at Etihad too, Liverpool have not won there in eight years. We prove, both sides we are incredible competitors. I would prefer a win but they prove for many years the quality they have. It was good from everyone."
