When the blue side of Manchester anticipated the fresh breath of a Champions League night on Tuesday, it felt different to recent seasons.
Unlike previous campaigns, Manchester City had a fresh look this season - every aspect of their squad rejuvenated to the core, mainly by fresh young signings.
City's stars came into this game on the back of flawless Premier League displays accompanied with barrels of confidence.

So, with that, came the expectation from City supporters - expectation that their beloved Sky Blues will get off to a flyer and continue their invincible start to the season.
Unfortunately, however, an all too familiar sight occurred instead - the sight of a seasoned Champions League team once again getting the better of City with superior tactical intelligence and unity.

You can, of course, argue that the Citizens were wasteful with their chances, most notably two golden Raheem Sterling opportunities, however Juventus were good value for their win.
The Old Lady unified against a pedestrian-looking City side that barely troubled the back four in terms of dragging them around. It was all played in front of them and was fairly easy to maintain.
Credit must go to the Italian champions. They prevented City from playing to the scintillating standard that they have shown in the Premier League this season.
The only reason City managed to break the deadlock was due to an own goal by Georgio Chillieni, hotly contested afterwards by Juventus players for a deemed climb on Vincent Kompany.
After this, City failed to maintain their lead and looked comfortable for all of five minutes until Juventus started to ask questions, with Mario Mandzukic tucking home superbly after a through ball to make it 1-1.
Their only real chance of the game so far, and just minutes later, Morata took advantage of a loose ball to place a curling shot past Joe Hart for the winner.
Not only was this a less-than-noteworthy performance by City in terms of attacking threat, but this match summed up their lack of professionalism in European games.
Always doing things the hard way, it was the exact same last season at home to Bayern Munich. Although City ended up winning the match 3-2, they were 1-0 up and failed to maintain it.
Xabi Alonso's free-kick along with a header from Robert Lewandowski were both preventable goals, representing another match where Pellegrini's men made it difficult for themselves.
If City continue this way in the Champions League, with such naivety and complacency, a steep mountain could await them in Group D.
However, there were positives to take, with Fernandinho performing superbly.
The Brazilian put in a man-of-the-match display, constantly breaking up Juventus' play and taking a lot of the responsibility in bursts forward.
The central midfielder was even unlucky not to score mid-way through the first half, running onto a dropping ball for a square volley, only to fire past the post.
Maturity and responsibility is needed, then, with Pellegrini facing a challenge to mentally prepare his team for their next European match following yet another setback.
