Guardiola warns opportunities for young guns must be earned

Young talents Phil Foden and Brahim Diaz were recently handed first-team debuts in the second half of the Champions League fixture against Feyenoord in midweek.

Guardiola has shown himself keen to rotate his squad if the players earn their chances: "If we give an opportunity to young players, it is because they deserve it. That is the most important thing."

"But one young player, you can say we helped them when they play regularly. If they play one or two games and then disappear that is nothing," he added. "It depends on our confidence and their confidence but the rest always depends on them."

"People say it depends on the manager but it depends on the players. The quality, how they live their professional lives, how they are, it is simple like that."
