"The manager was saying before that the more and more he plays the Champions League, it is about the set-pieces", Stones said.
Tiemoue Bakayoko's thumping header fired Monaco into the Champions League quarter-finals as Wednesday's 3-1 victory condemned Pep Guardiola's Manchester City to a painful exit on away goals.
"It is a massive disappointment", right back Bacary Sagna said.
But despite City travelling to Stade Louis II needing only to defend their two-goal first-leg lead to qualify for the quarterfinals, centre-half Kompany was not included in the matchday squad by Guardiola. "We gave them too much respect and ... we put ourselves in danger". But six minutes later Bakayoko rose imperiously to meet Thomas Lemar's curling free kick and restore the two-goal margin Monaco needed as the contest finished 6-6 on aggregate. It's the same situation for Pablo Zabaleta, who remained on the bench as City's pursuit of a first European Cup ended in the round of 16. We did it in the second half, we did it in a lot of games, even when we lost.
Andrea Raggi made a crucial interception to deny Sergio Aguero, who had been teed up by Sterling, and keeper Danijel Subasic then produced a superb save to deny the Argentine striker in a oneonone.
"The big difference coming here is that there are a lot of teams with lots of money and lots of good players".
Guardiola has built arguably the greatest attacking force now in the Premier League - with Kevin De Bruyne, David Silva, Leroy Sane, Raheem Sterling, Sergio Aguero, Gabriel Jesus and Nolito all top class offensive options - but his defensive unit is remarkably poor. But Guardiola has been reassured by the reaction from City's powerbrokers. He prefers to win the Champions League, he was not there (at the game) but he is always close (to me).
Paul Merson is tipping Manchester City to secure a 3-2 win over Liverpool in the Premier League at The Etihad on Sunday afternoon.
City go into the weekend third in the Premier League table, one point above fourth-place Liverpool with a game in hand.
Asked whether he would be more defensive against Liverpool, Guardiola said: "No, no". "I expect more desire, to show more passion". It was also another really good generation at Bayern Munich, there was not a second team in Germany, we tried to be it but it didn't happen. "Now we are very happy".
Don't discount Arsenal from forcing either Liverpool or City from the Premier League's top four. They face a critical run of games, with the visit of Liverpool followed by matches away to Arsenal and Liverpool after the worldwide break.
