Manchester City striker Sergio Aguero will be out for up to 10 days because the Argentine striker is still isolating after coming into close contact with someone who tested positive for Covid-19, manager Pep Guardiola said on Tuesday.

“He’s isolating,” Guardiola said ahead of Wednesday’s Premier League game at home to Brighton & Hove Albion. “(He is following) the rules. After nine or 10 days he will be back.”

City, who are fifth in the table with 29 points from 15 games, have midfielder Raheem Sterling available.

The team has won their previous six games in all competitions, including wins at Chelsea and Manchester United, but Guardiola said his players must guard against complacency.

“The momentum arrives and disappears in one instant,” he added. “We cannot forget the teams we beat recently, especially in the Premier League... But the momentum can disappear tomorrow so we have to do it again.”
