Manchester City manager Pep Guardiola has confirmed his star player Kevin De Bruyne has picked up an injury in his side's 3-1 victory over Swansea City in the Premier League at the Liberty Stadium on 24 September.

The Etihad outfit faced the Welsh club for the second time in less than a week, with the first fixture ending in a 2-1 win for City in the EFL Cup. The Belgium international, helped Guardiola's side win the penalty, which resulted in City's second goal.

However, De Bruyne could not complete 90 minutes and was replaced by Jesus Navas in the 81st minute. The Catalan admitted the former Chelsea man picked up a muscular injury and will undergo tests to assess the damage.

"I think he's injured. Tonight, we are going to come back to Manchester; tomorrow, the doctor is going to see. It's a pity. It's important for us. Yeah I think so. For how he reacted, it looks muscular, but I'm not a doctor fortunately," Guardiola said, as quoted by the Manchester Evening News.

De Bruyne has already managed two goals and four assists from six league matches. Should the 25-year-old set for a spell on the sidelines, his absence will be a massive blow for City in their upcoming fixtures.

Meanwhile, the former Barcelona and Bayern Munich manager stressed that he will be rotating between Bacary Sagna and Pablo Zabaleta in the right-back position. The Argentine replaced the ex-Arsenal defender in the second half against Swansea.

"I trust a lot with Bacary Sagna, I trust a lot with Pablo Zabaleta. We cannot forget that Pablo was last season five or six months out. He came back for the national team [last month] perfect, so now it's the best moment for Pablo," the City manager explained.

"We cannot forget how many games Bacary Sagna played last season because Pablo was injured and he played absolutely everything and then went with the national team and played absolutely everything in the European Cup and after had just 12 days' holiday and we are in September. I want to, especially in that position, make a rotation in the players," he added.
