Those results have us top of Group G with a maximum nine points, three ahead of Leipzig in second on six points with Young Boys and Red Star trailing in third and fourth respectively on the solitary point.
City are one of only four teams to boast a perfect record in the 2023/24 competition, alongside Bayern Munich, Barcelona and Real Madrid.
