Cape Town - Manchester City will be without star striker Sergio Aguero for a month following his knee ligament injury, reports the Mirror.
The Argentine striker limped off during Saturday's victory over Everton and will miss their crunch Champions League tie in Rome on Wednesday.
But the City boss has called on his players to use the enforced loss of Aguero as a chance to show they are not wholly reliant on the Argentina striker and can win in adversity without him.
“Every big team must have important players like Sergio,” said Pellegrini.
“I suppose Cristiano Ronaldo is very important for Real Madrid, Lionel Messi is very important for Barcelona, but neither of those teams are all about just one player.
“I don’t know if that is the correct perception about us. It’s one thing that a player can be in a very good moment, as Sergio was until this injury, but I don’t think he has carried us.
“We have beaten a very difficult team like Everton without Sergio, without Silva, without Kompany, without Stevan Jovetic and with Edin Dzeko only able to play the last 25 minutes.
“We would prefer to play with Sergio, but if he cannot play we must try to continue the same way we have been playing in the last week. Remember, last season we played a lot of games without Sergio – and these are the same players and the same team.
“So I hope we can recover from this important injury but we have a good squad and we will see how we can do it.
“The confidence is very high in this moment for the whole team, but the injuries mean it is not the best way to approach such an important game as Roma. But I have confidence in this team and I hope we will do it in the same way that we have won these last five games.”
