I actually do not know how long Kelvin De Bruyne is gonna be sidelined because of the injury he picked last time in the first half of their first English Premier League match of the season but I trust that Pep Guardiola knows how to perfectly handle his absence from the club.
But if he thinks there's no other player in Manchester City's squad that can replace the injured Belgian, City should then sign another creative midfielder that can do the things he does for the club.
It is reported that Kevin De Bruyne will be absent for the next four months, if he has to undergo surgery. It is very possible that Man City will add new players in the remaining time of the transfer market, Lucas Paqueta is the talk for now. Reportedly Westham will not release his players at a low price, the price reaches 90 million euros.
There are several other names that are being linked with the potential to replace De Bruyne's role, including Florian Wirtz (Bayer Leverkusen), Khvicha Kvaratskhelia (Napoli), Julian Brandt (Borussia Dortmund). But Lucas Paqueta is in first place I think, because Man City has previously made an offer to West Ham.
