Manchester City have the attacking options to cope with the absence of first-choice striker Sergio Aguero, manager Manuel Pellegrini said while admitting the Argentine is impossible to replace.

After a quiet start to the campaign, Aguero scored five goals in the 6-1 win over Newcastle this month but much to City’s dismay he tore a muscle in his left thigh while on international duty.

With the injury set to keep Aguero on the sidelines for a month, Pellegrini is confident he can bank on his other strikers, Wilfried Bony and 19-year-old Kelechi Iheanacho.

“Kun (Aguero) is impossible to replace but we know we have another option in attack,” Pellegrini said.

“I think this moment it’s important for the team to have Kelechi and Bony as options without Kun.

“They can play both together as they did tonight. Bony played well tonight. Of course Kelechi was very impressive but Wilfried is quiet as he knows he has my trust.”

City have scored 12 goals in four games without Aguero and Pellegrini praised Iheanacho after his strong display against Palace, with the Nigerian scoring one goal and setting up two.

“It was very important for Kelechi to demonstrate once again that he’s a very good player. He has things to improve but he’s working in the correct way,” Pellegrini said.
