MANUEL AKANJI will have surgery on a groin injury on Saturday and faces a fight to return before the end of the season.
Manchester City’s Swiss defender limped out of the Champions League defeat to Real Madrid on Tuesday and has been assessed this week.
He said: “With Jack, it’s not as bad as Manu has done but I don’t think he will be ready for Saturday.
Boss Pep Guardiola has had to deal with injuries to most of his defenders this season and believes the extra workload has caught up with Akanji.
