Pep Guardiola expressed satisfaction with the performance and outcome as Manchester City secured top spot in their Champions League group with a goalless draw at Porto.

City were not at their exhilarating best on Tuesday but, with qualification for the last 16 achieved with two games to spare, they were under little pressure at the Estadio do Dragao.

Porto, needing just a point themselves to join City in the knockout stages, also appeared to set their stall out for a draw and they frustrated the visitors by defending stoically throughout.

He said: “We achieved qualification with an impressive series of games on our part.

“It is our 16th time in the round of 16, more than double that of all other Portuguese teams. We carry the name of Portugal in Europe very high.

“We showed good moments of defensive organisation tonight, although it was difficult to get up front as we wanted – much because of City, who react well when they lose the ball.”
