Tottenham manager Jose Mourinho told BBC Sport: "It feels good [to be top], but maybe tomorrow we are second again and honestly that would not be a problem for me, I am just happy with the evolution.
"People cannot expect us to come here and after one season we are fighting for the title. We are not fighting for the title, we are just fighting to win every match. But we are going to lose matches, we are going to draw matches.
"Dinner tonight will be nice and relaxed and I will watch Atletico Madrid v Barcelona and sleep like an angel. But no problem if Leicester wins [on Sunday] and we are second again."
Manchester City manager Pep Guardiola said: "It could be better, we played similar to how we have all season. We did not defend good for the first goal. They then defended so deep, they defended with six and it was not easy. We had our chances, but we couldn't score and they made two or three chances on the counter-attack and we lost the game.
"We knew before the game that you cannot give them the first goal. We had more chances than them but we lost. Mourinho's teams are like this, you make a mistake and they punish you on the counter-attack."
