Monaco upset the odds again on Wednesday night as they knocked Manchester City out of the Champions League on away goals after drawing the tie 6-6 on aggregate.Pep Guardiola's City were certainly the favourites for the tie given the Spaniard's pedigree in the competition.City's failure marks the first time in Guardiola's managerial career that he failed to make the semi-finals of the Champions League, let alone the last eight.The secret behind the Principality's success lied in the belief in their young starlets that more than rose to the occasion.Kylian Mbappe is, undoubtedly, the cream of the crop and has been hailed as the new Thierry Henry thanks to his lightning pace, composure and finishing ability.He has eleven goals in his last eleven appearances and for an 18-year-old to have 17 strikes this season and eight assists, that pretty much out of this world.But there's more to Monaco than him. Tiemoue Bakayoko - scorer of the decisive goal in the tie - Benjamin Mendy, Djibril Sidibe and Thomas Lemar are all young Frenchmen who have established themselves for the Ligue 1 heavyweights and will be worth a lot of money very soon.Part of their success lies in their camaraderie and the journey they have all been on together. That much was evident in their post-match celebrations that were posted on Twitter.

Although it looks like Roy Keane's worst nightmare, the French side thoroughly enjoyed their progress into the last eight and the changing room videos show them beyond ecstatic with the result.

The draw for the quarter-finals of the Champions League are around lunchtime on Friday and Monaco enter the draw as one of the less-fancied sides compared to the likes of Bayern Munich, Barcelona and Real Madrid.

But, after overcoming City over two legs, no side will actively fancy taking on the young stars of Monaco.
