Manchester City defender Pablo Zabaleta believes the axing of Joe Hart for the 7-0 victory over Norwich is a reminder of the high standards expected at the Etihad Stadium.
The England goalkeeper paid the price for his costly last-minute mix-up with Matija Nastasic at Chelsea - the latest in a long line of errors - by losing his place to Costel Pantilimon on Saturday.
Zabaleta said: "Well, you know, that is football. The manager makes decisions.
"We know in this team now the performance of everyone should be good week in, week out because we have two players in each position who can play.
"Sometimes mistakes might cost the place but we are a big squad and we need to try to do well to keep the place in the team.
"I think it was great for Costel. He is a man who works really hard in the week. He well deserved the place."
Zabaleta also felt the result and performance were the perfect response to the late slip at Chelsea.
The Argentinian added: "I think it was a great performance by the team. We needed to respond well after the Chelsea defeat, that was hard for us.
"I think the performance was great. Defending - it was important to keep the clean sheet, and we were on fire in attack. I think it was a great game.
"It is another three points, that is good, and we look forward now to the Champions League game.
"We feel very comfortable at home and our performances have been great since the start of the season.
"Playing away we have dropped too many points but when we play at home we are a very strong side."
