Champions League live scores, updates: Kylian Mbappé puts Real Madrid ahead of Inter Milan; Porto frustrating Manchester City

Brothers Ethan and Kylian made first-half impacts helping their respective teams to early leads. Prior to the match against Inter Milan, Kylian Mbappé received the Golden Boot award for leading last season's Champions League in goals.
