Manchester City manager Manuel Pellegrini has revealed that Sergio Aguero will miss the vital midweek Champions League game against Roma after coming off injured in Saturday's 1-0 win over Everton.
James Milner was fouled by England teammate Phil Jagielka for the penalty from which Yaya Toure netted the winner and closed the gap behind the Premier League leaders -- beaten 2-1 by Newcastle earlier in the day -- to three points.
But the early injury to Aguero -- who left the field in tears -- overshadowed the game, and Pellegrini is pessimistic over the striker's knee problem.
"He has a problem in his ligament, in his knee," said Pellegrini. "We will see tomorrow how serious it is but it's not good news, I don't think he will be able to play next week.
"We must wait for the doctor but the important thing is he will not be playing against Roma and it's a very important game for us.
"But we have other players and we will rearrange if he does not play."
Pozo was chosen ahead of Edin Dzeko to replace Aguero before later giving way to the Bosnian, who has been suffering with a calf injury, with Pellegrini explaining: "Edin was not able to play 70 or 80 minutes, he could play a maximum of 35 minutes.''
Milner savoured an important response to Chelsea's first defeat of the season as City edged a win over the Toffees, telling Sky Sports 1: "It's very important. We were aware of the result but all we can control is what we do on the pitch.
"It's pleasing that we got the result after their result earlier on. It would have been very easy to slip up after seeing that result and being happy they dropped points, and we've played better recently than we did today but we did our job and got the result.''
Regarding the penalty, he said: "I played on but I think there was contact, Jags tried to stop himself as he was coming in but I think outside the box it would have been a free-kick."
The one negative was an early injury to star striker Sergio Aguero and Milner said: "He's a top player and losing him early disrupts the plans a little but I think Jose [Pozo] did a good job in the time he was on, it's not easy replacing Sergio Aguero."
