Manchester City maintained a perfect start to their Champions League campaign as Gabriel Jesus scored on his return in a 3-0 victory over Olympiakos at the Etihad
Ferran Torres scored in his fourth consecutive game in the competition to give Pep Guardiola's side the lead after just 12 minutes, but the contest did not evolve into the formality City's fast start had promised
Mathieu Valbuena missed a glorious chance to level 10 minutes into the second period before Jesus came off the bench to settle the contest with an unstoppable finish from a tight angle (81)
City added a third as fellow substitute Joao Cancelo's speculative drive surprised Jose Sa (90) to cap a routine win that preserves their 100 per cent record from three group stage matches ahead of facing Liverpool on Super Sunday, live on 
Olympiakos remain third in Group C while Porto are three points behind City in second place after winning 3-0 against Marseille on Tuesday
Olympiakos entered the game without Kostas Fortounis through injury and with a dismal record in England having won just twice in 17 visits, but the most recent of those wins came against Arsenal in the Europa League in February
City have scored 23 goals this term - 13 fewer than they had plundered this time last year - but there's a growing feeling they are now slipping into gear after an inauspicious start
 Guardiola's men are looking increasingly capable of steel as well as silk and led 1-0 at the break
The hosts went straight onto the front foot and had already threatened through Phil Foden, Riyad Mahrez and Kevin De Bruyne when Torres, starting as a lone striker, put City into a deserved lead within 12 minutes
The goal came as the Spaniard played a good one-two with De Bruyne and then calmly side-footed through the legs of Sa
Even with five changes to the side that edged Sheffield United last Saturday, City were a cut above their Greek opponents
 Olympiakos were indebted to Sa as he twice smothered inviting crosses with Raheem Sterling ready to pounce on both occasions - but City's advantage at the interval was a slender one despite their dominance
Olympiakos manager Pedro Martins made a double change at the break involving Bruma, and the winger on loan from PSV Eindhoven transformed the visitors in the second period
City, by contrast, were pedestrian as their recent lack of cutting edge that has seen them score just four times in their last four Premier League games was again evident
Foden's blind pass from Ederson to John Stones as City played out from the back was pounced on by the veteran Valbuena but the 36-year-old sliced his effort wide having been surprised himself by the gift
By then, Mady Camara had already just failed to connect with Valbuena's corner but Jesus' introduction with 22 minutes remaining helped City rediscover their focal point as a second goal duly snuffed out any hopes of a shock Olympiakos revival
Inevitably, De Bryune was involved as the Belgian fed Jesus down the right of the penalty area
 The returning Brazilian fashioned a yard of space and the sheer velocity of his shot took the ball away from Sa at his near post and into the roof of the net
There was still time for a third to somewhat flatter City despite their 16 attempts - a ninth in three Champions League games in contrast to their recent domestic struggles to find the net - as Cancelo collected the ball in midfield, drove forward and curled a 25-yard strike with his left foot into the corner
Manchester City boss  told : "In the first half, we played really well
 In the second half, we struggled for some moments but when we scored the second one it was over
"We've had a good three games, nine points
 We need three more points or one more point to qualify
 We have five days to recover for Liverpool and then the international break
"They had one or two chances [to equalise]
 When we controlled in the way we control, we cannot finish games - we struggle with the second goal - but finally with an incredible goal from Gabriel Jesus and then from Joao Cancelo we win the game
"John Stones is back, an incredible performance - almost perfect
 It's not easy when you're a long time without playing
"The forecast in the next three days says it will be sunny in Manchester
 It's rare
 We're going to have tomorrow off
 After that on Friday and Saturday we'll prepare for the Liverpool game
 But the players need a break
"Torres tormented the Olympiakos defence, dropping deep and arriving late in the box during another impressive display which included three key passes for his team-mates
Moved to the right following Jesus' arrival, the 20-year-old returned to his natural position having shown his versatility and capped another lively display with his third goal in four games - one of five shots, more than any other player
Aged 20 years and 248 days, the Spaniard is the third-youngest player in Champions League history to score in four consecutive appearances, behind Kylian Mbappé (18y 120d) and Erling Haaland (19y 107d)
