England global John Stones has also struggled with injury this season thereby forcing manager Pep Guardiola to field defensive midfielder Fernandinho in the centre back position this season.
Do City need more defenders?
City's first-choice centre-backs Stones and Laporte have both picked up serious injuries.
But Guardiola insists City can not afford to sign another defender in January.
Spain midfielder Rodri, however, does not want to use their spate of defensive injuries as an "excuse" for City, who won their Champions League opener 3-0 at Ukraine's Shakhtar Donetsk.
Asked by Sky Sports whether he is looking to invest once the transfer window reopens, Guardiola stated: "That is not my business, but in January we are not going to buy because we don't have money to pay a huge amount in the summer, so we can not do it in winter".
Gabriel Jesus voiced his unhappiness to Brazilian TV.
"That is not my business but in January, we are not going to buy because we don't have money to pay a huge amount in the summer so we can not do it in winter".
Guardiola had vowed to stay with kids Taylor Harwood-Bellis and Eric Garcia - both of whom began and helped maintain a clean sheet in City's third-round success over Preston at the League Cup.
"Vinny was an incredible personality and he was incredibly helpful to me and the whole club, Guardiola explained".
"He's passionate. I read that interview and it was flawless", Guardiola told a pre-match news conference.
"They purchased Aymeric Laporte in January a year and a half before, and I believe they're going to get to do exactly the same again".
"Guardiola will understand it - he understands the standard greater than anyone". "I saw this morning that Guardiola said they didn't have any money".
City have been so good within the opening 25 minutes right here that it regarded like being a really lengthy afternoon certainly for Everton however Marco Silva's aspect rallied and, in the long run, Guardiola was as indebted to the brilliance of his goalkeeper, Ederson, as he was Mahrez's majesty going ahead.
