Pep Guardiola insists Manchester City do not need to buy in the remaining weeks of the summer market.
Asked about pundit suggestions following the Tottenham match that City would need to sign more players to improve, Guardiola was dismissive.
He said: “I don't have any doubts.
“What they (his players) have done so far, many, many years…the main group of the people is the same. I know their mentality, I know they want to do it, and tomorrow with our people, of course we want to do it.
“Football is unpredictable, and everything can happen, and the bad periods can happen again. So we will see.
“But I am more than optimistic (from) what they have done since they arrived, and step by step we will improve."
