Everton boss Roberto Martinez admits they face a huge test keeping Manchester City ace Sergio Aguero quiet.
Everton travel to the Etihad for the 5.30pm kick-off looking to avenge losing leads and points against Tottenham and Hull City.
Martinez said: "Sergio is a phenomenal talent and is one of those players who can single-handedly win you the game.
"We'll have to be very, very aware of that on Saturday because I think City are now playing the best football of this campaign. They have a real good feeling about themselves since their win against Bayern Munich.
"You saw a real change in the confidence of their group and since that day, they have played with a real flair and swagger. They are one of the hardest teams to face in the Premier League, alongside Chelsea.
"It will be difficult, but we went to Spurs and didn't get what we deserved. Against Hull, we only got one point and it gives you a real desire to go out there and face a difficult opponent. If you do the right things, we'll get a bit of luck and some reward."
