Manchester City boss Manuel Pellegrini has warned against complacency when his side host Dynamo Kiev on Tuesday night.
The Citizens registered an important 3-1 scoreline away from home and are strong favourites to make it through to the next round of the Champions League.
But the Chilean says his players have to be fully focused if they are to qualify for the next round.
"Yaya [Toure] is fit to play tomorrow. He has no problems," Pellegrini said.
"[Samir] Nasri, [Fabian] Delph and [Kevin] De Bruyne, I expect they can play a friendly game during the international break.
"We talked yesterday and today about what we must do tomorrow. We're not going to play with the score we got in Kyiv, we're just going to say it's 0-0 and try to win the game tomorrow. That's how we approach it.
"The most important thing is to know we have not qualified already. We play against a big team who know how to play this type of game. That's the first target, then we see who we'd play in the next round. With the trust and confidence, we continue.
"When you achieve a good achievement that you couldn't do before, it gives more experience and confidence. It was important to win the group and I'm sure this group wants to keep making new achievements.
"We've improved in the competition.
"Before I arrived here, the club didn't qualify for the Round of 16 but we've did it twice in the first two years with Bayern Munich in our group both times and we won two and lost two against them."
