Sergio Aguero is set to miss Manchester City’s League Cup quarter-final clash against Hull on Tuesday night, Football Insider sources understand.

The Argentine left Etihad Stadium on crutches on Saturday after limping out of his team’s 3-1 over Southampton that afternoon.

Manager Manuel Pellegrini said his leading striker was kicked on the heel but was about to be replaced by Wilfried Bony even before sustaining the injury an hour into the clash.

A City source has told Football Insider that Aguero was assessed by club medics on Sunday and they are confident his absence will only be a short one.

Last season’s 26-goal Golden Boot winner is expected to miss the quarter-final against Hull at Etihad Stadium and is also a doubt for Saturday’s Premier League trip to Stoke.

But the club are convinced Aguero will be fully fit next week.

The Argentina international has only just returned to action after missing six weeks with a hamstring injury he sustained on international duty.

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

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.
