Pep Guardiola hailed his Manchester City side despite them drawing blank in their tight goalless Champions League clash with Porto which saw them confirmed as group winners.
City had already secured qualification for the last 16 with two games remaining, and faced little threat from the hosts at the back at the Estadio do Dragao.
But Guardiola's side were unable to force a way through and make it five wins from as many group matches, with Ruben Dias missing from a yard out and Gabriel Jesus having a goal ruled out for offside.
