Manchester City are sweating over Sergio Aguero’s fitness yet again after the striker limped off during their 3-1 win over Southampton on Saturday.

The Argentine only returned last weekend after missing six weeks with a hamstring injury he sustained on international duty.

Aguero was competing for an aerial challenge just after the hour mark before he appeared to land awkwardly on his ankle.

He was replaced after 64 minutes by Wilfried Bony, who was making his comeback after three weeks out with hamstring problem of his own.

But City manager Manuel Pellegrini shrugged off concerns that Aguero could face another lengthy absence as he explained that the striker’s withdrawal was merely a precaution.

“I spoke with him before the game and we said he would play 65 minutes,” Pellegrini said at his post-match press conference on Saturday evening. “He has a kick in his heel, but nothing important.”

City are already without key players in Joe Hart, Vincent Kompany, Eliaquim Mangala and Pablo Zabaleta, as well as Samir Nasri, who is facing a battle to play again this season.

David Silva made his long-awaited return against Southampton from an ankle injury that had sidelined him for two months. The Spaniard playedthe last 15 minutes after replacing Raheem Sterling.
