Manchester City have one firm foot in the group stages of the Champions League, after their 5-0 demolition of Steaua Bucharest.
It was a game dominated by striker Sergio Aguero, as David Silva's opener was sandwiched between two penalty misses from the Argentine, who added one just before the break.
Nolito added a third in the second half, and Aguero added another two in a ten-minute period right at the death to all but secure City's passage into the group stages.
Many will have expected Pep Guardiola's side to breeze through the play-off against their Romanian opponents, and they had the opportunity to take the lead after eight minutes.
It was an easy decision for referee Daniel Orsato to give a penalty, after Raheem Sterling was hacked down by Sulley Muniru. Aguero stood over spot kick but it proved easy to save for Florin Nita, and the follow-up clattered the crossbar.
Luckily for Guardiola, Silva had his shooting boots on as he gave City the lead. It was good pressing from Sterling who dispossessed the dawdling defender, and did well to cut it back for the Spaniard to slot home.
Aguero was handed another opportunity to score from the spot, after the dangerous Sterling was hacked down. But once again the Argentine was off target as he blazed the effort over the crossbar.
Turning the screw
City proved to be completely as they looked to kill off the game and the tie in the opening 45 minutes, and had some good opportunities to add to the scoreline.
Aleksander Kolarov's deflected effort looked to have got the best of Nita, as it looked to be looping into the net, but luckily for the keeper, it nestled on the roof of the net.
Kolarov was at again six minutes from the break, as he met a corner with a volley from close-range, but only managed to clatter the post.
It was then the turn of the Sterling to hit the woodwork seconds later, the English winger had arguably been City's best player and was at it again. He managed to slide through the defence and looked to have chipped Nita, but a vital touch saw it come off the crossbar.
Third time lucky
A lesser striker would have let two penalty misses affect their confidence, but not Aguero as he scored at the third time of asking.
It was a excellent finish, as the ball was put on a plate to him by Sterling, and Argentine finished well by firing first-time into the bottom corner.
Getting off the mark
City certainly didn't take their foot off the gas as the came out for the second period, as they added a third just four minutes after the restart.
It will have been a first goal to remember for Nolitio, Kevin De Bruyne played an excellent ball into the Spaniard who coolly took it around the keeper and slotted into a empty net.
They took their foot off the gas as the half went on, but Aguero secured an excellent win by adding two more goals to the tally.
His second and City's fourth came in the 78th minute and it was a simple finish, one-touch football resulted in the ball been chipped over to the striker and made no mistake by firing into the far corner.
The final goal on the night came a minute from time, Bucharest's defence had been all over the place for the majority of the evening. Their weaknesses were exploited once again as Aguero was allowed to finish off at the post to round off an excellent European debut for Guardiola.
