Manchester City boss Pep Guardiola have seen his squad beat Southampton 6-1 to return to the top of the Premier League on Sunday.
“We played excellently, without and especially with the ball," he told BBC Sport after the game.
"We were aggressive in the final third, but we were lucky to score the goal in the last minute of the first half (through Sterling).
"The game was not over, because we concede. Southampton created more chances than most teams this season."
Guardiola said that Southampton includes the best corner taker in the Premier League in their ranks.
"The team showed me some signals that in some positions we are not stable enough," he continued.
"We played with the ball so good but not without the ball. We were not stable behind. We concede a lot of corner kicks and with the best taker in the league [James Ward-Prowse] like Southampton had."
