Leicester City boss Ruud van Nistelrooy says they need to be at their best against Manchester City.
The Foxes host the struggling title holders in Sunday's early kick-off.
“Everyone knows, when you look at the team and how they played (against Everton), I know the quality of this team and their manager so I focus on that and the quality we will face” , said Van Nistelrooy.
“We have to prepare ourselves for a good performance from our side. Being where we are, we have to be perfect in every area of football to get a result.
“For us, every game we play is huge. We know that a certain number of points are needed and that every second of every match is important.
“It’s something that requires constant improvement and pressure to perform and achieve results. It's game to game, we evaluate the game and come up with a game plan to get a result against City.
The Foxes could have Jamie Vardy back on Sunday after the veteran striker missed the Boxing Day defeat at Liverpool.
“Jamie had a little injury, a few knocks last week,” Van Nistelrooy said.
“He wasn't fully fit at Liverpool so we gave him time to recover. I hope he can be there on Sunday. He has a good chance.
