Everton must earn victory over City - Leighton Baines
Defender Leighton Baines says Everton's good record against Manchester City will count for little when the clubs meet at Eastlands on Saturday.
Baines' team have won their last four games against Roberto Mancini's men.
"We're fully aware that we must treat every game individually, so we don't take anything for granted," Baines told BBC Radio Merseyside.
"We'll use our past games for some confidence but we've got to go there and earn whatever we get."
He added: "It's a big game at the weekend for us and City have been doing really well.
"But we'll take confidence from the results we've had against them in the past and we'll draw on that going into the game. Then we've got a tough run of games as well over the next few weeks."
Everton advanced to the last 16 of the Carling Cup thanks to Wednesday's 2-1 win over West Brom after extra time.
The England defender believes his team were worthy of the victory and were determined to keep their winning momentum going.
"We're happy to be in the draw for the next round and this cup run is important to us," Baines continued.
"I think you could see that towards the end of the game and we fought hard to get the equaliser. We did quite well tonight and it's nice to be in the hat.
"It's important that we've kept our momentum going tonight and hopefully we can build on it."
