The arrival of Pep Guardiola was decisive for Barcelona's success. The coach was afforded signings worth millions, but above all he gave opportunities to several youth squad players that marked the future of the club.
After arriving at Bayern Munich, Pep continued to try to give opportunities to younger players but ended up betting on the old favourites, which gave him great results in Germany, but not so much in Europe.
Manchester City have also failed to shine on a continental level. Although they have managed to become invincible in England, the club has not been able to export its success to Europe, where the sky-blues have suffered elimination after elimination in a surprising way.
Guardiola has once again missed out on utilising the youth academy. Only Phil Foden has a chance to show his quality on a regular basis and others like Zinchenko, who signed for the second team, have had opportunities.
However, the legendary coach has a long list of players who could have triumphed in the team.
The cases of Iheanacho, Brahim and Sancho are the most striking, but Gunn, Denayer, Rekik, Angeliño, Denis Suarez and Brooks were also at Manchester City's youth academy. Even Trippier and Karius were there, although well before Guardiola made it to the first team.
Despite what he has achieved across his various clubs, the critics are still homing in on his reluctance to use the youth players. Pair that with the rumours that could see him bid farewell to City, and we have another story on our hands.
