Manchester City's hopes for a Quadruple this season continued as they cruised into the Champions League quarter-finals, winning 2-0 in the second leg of their last-16 tie against Borussia Monchengladbach and 4-0 on aggregate
Pep Guardiola's side were dominant over both matches and it took just 12 minutes to add to their 2-0 aggregate lead from the first leg
 Kevin De Bruyne powered home via the underside of the crossbar as City extended their advantage
Soon after, Gundogan added a fine curled finish around Gladbach goalkeeper Yann Sommer, scoring his 15th goal of the season
Gladbach - who have now lost their last seven games in a row across all competitions, their worst losing run since losing eight in a row between September and November 1989 - had a few sights of goal, but nothing that ever truly troubled the Man City defence as they breezed into the last eight
They will now be in the hat for the Champions League quarter-final and semi-final draw on Friday, as their march towards the Istanbul final continues
Both sides had sights of goal in the opening 10 minutes
 Joao Cancelo played a sublime ball over the top for Phil Foden, but his flick was saved well by Sommer
 At the other end, Breel Embolo tested Ederson from range, with his effort pinging off the leg of John Stones and forcing a fingertip save from the Man City goalkeeper
But Man City's superior quality started to shine through and they took the lead in emphatic fashion in the 12th minute
 Mahrez darted away from two defenders before rolling the ball through for De Bruyne at the top of the area
 The Belgian, on his 45th Champions League appearance, then set himself up beautifully before hammering his shot onto the underside of the crossbar and into the back of the net
Soon after, it was two
 Foden drove through midfield before playing a superb diagonal pass for Gundogan waiting in the box
 The German drove onto it before curling the ball sweetly around the oncoming Sommer, scoring his 11th goal in all competitions since the turn of the year
Embolo again kept Ederson occupied as the clock ticked past the half an hour mark
 He held the ball up well on the left before curling a shot around Kyle Walker, but it was straight at the goalkeeper
 A few minutes later, De Bruyne delivered a stunning free-kick, but Sommer made an acrobatic save to tip it over the crossbar
Mahrez had numerous chances in the second half, but could not find the third for Man City
 Inside three minutes, Gundogan slid the ball into his feet, but he dragged his shot wide, despite having options on either side
The Algerian was then thwarted twice by Sommer in quick succession
 The first was pushed away by the Swiss international, but Bernardo Silva kept the loose ball alive
 He picked out Mahrez again, but his cross was cleared away by Lainer
 Then, some sensational build-up play from Foden saw his cut-back land to Mahrez, but his effort went straight at Sommer this time
Gladbach had a few late efforts, but none were particularly close
 Hannes Wolf fired well wide before Alassane Plea picked out Ibrahima Traore superbly inside the area, but the latter dragged his shot well wide
The game ended with two efforts sent wide by Mahrez as City cruised into the last eight
It's hard to look past De Bruyne when he's playing so well
 His goal was wonderful, and he could have had another with his first-half free-kick
 De Bruyne had two shots on target and made three key passes, having now been involved in 12 goals in his last 11 Champions League appearances (3 goals, 9 assists)
 He will be vital if Man City are to reach the final
"Sometimes it looks very easy afterwards
 It was a good performance, under control for the 90 minutes and we arrived here with a good result [from the first leg], but this competition is tricky
"We are so serious and after the two magnificent goals, it was easier but the way we played was really good
 Everyone in their positions, we moved the ball quick… and there are a lot of good players with good quality who don't lose the ball
 That is what we need… Everyone was so committed and [we are] delighted to be in the next stage
"What happened in the past is in the past
 In the quarter-finals, one bad game, bad minutes, bad moments, they can punish you
 The quality right now with all the teams will be so big
"In the previous seasons, I didn't see a team that didn't want to make a step forward
 Every time we play, even in the group stage or last 16, we want to go through
 After the international break, we have time to think - it depends on the draw of the team - but now, the best teams in Europe, the quality is higher every time and it is more difficult
"But hopefully the team can maintain this mood, we can compete and especially play a good game
 I believe that when you go through, you deserve it and you have to play good games so we arrive there and try to play good enough
 We'll see what happens
" "There was lots of confidence but we have to recognise an opponent that was too strong for us
"The team tried to do what they could
 We had shots but if you allow City to have shots then you won't get very far
 We have to take chances if we get them
"We came here with a good feeling but then we faced this quality
 The lads are disappointed and there won't seem to be any positives at the moment, but there are positives we can take for the next weeks
"The most important thing for me, even though Man City were far superior, was the way the lads put effort into the game and stood up
 It is just difficult against that team
"The Champions League quarter-final and semi-final draw will take place from 11am UK time on Friday, March 19
