Manchester City became the first team in Champions League history to lead an away knockout game by four goals at half-time after a blistering opening 45 minutes against Sporting CP.
Riyad Mahrez got City on their way after seven minutes on Tuesday before Bernardo Silva doubled their advantage with a sublime half-volley 10 minutes later.
Phil Foden added a third shortly after the half-hour mark as City’s dominance continued.
Silva then netted his second shortly before the interval as Pep Guardiola’s side wrote their names into the record books once again.
