Manchester City recorded an emphatic 4-1 victory over Liverpool at Anfield to boost their title hopes.
Gundogan missed from the spot in the first half after Fabinho fouled Raheem Sterling to go into the restart with a goalless draw.
Gundogan scored a brace while Sterling and Foden added the other goals to seal the victory for Man City.
Guardiola has showered encomiums on his players for earning a ‘huge’ win over the defending Champions.
“Huge victory for us. Three more points at the end but I take into consideration the fact we won after we missed a penalty and conceded a goal. The way we reacted, that made the difference,” Guardiola said.
“Second half we adjusted our set up and the quality of the players did the rest.
“For many years we were not able to win here, hopefully next time we can do it with people inside. Anfield is so intimidating.”
