Ilkay Gundogan scored in each half as Bernardo Silva and Sergio Aguero also weighed in on Manchester City's latest attacking masterclass.
Manchester City took a giant step towards the quarter-finals of the Champions League with a 4-0 thrashing of Basel at St Jakob-Park.
Pep Guardiola's side tore Leicester City to pieces 5-1 in the Premier League at the weekend and resumed in similarly menacing mood against the Swiss champions.
Basel were left to rue Dimitri Oberlin failing to punish City's early defensive vulnerability and having a penalty shout turned down as a blistering spell of three goals in the space of nine first-half minutes from Ilkay Gundogan, Bernardo Silva and Sergio Aguero took the game away from them.
