The key point, for people still missing it, is that rotation isn't just about injuries and fitness, though it is that. It's about managing the squad, keeping the whole dressing room happy, and keeping every played match day fit.
Pep apologised to players, players like Cancelo and Rodri and Sterling, who have been crucial to our season but didn't get picked against PSG, what every player understood as our biggest game so far. He repaid that by telling them to go out and win the league yesterday. It's all well good only playing our first 11, but what happened when Sterling comes in for the final and hasn't played for 3 months or the management team have no recorded data on him?
My only worry from yesterday is that we have a lot of players whose confidence is down, and while we getting rid of some in the summer, many of those will not be going anywhere and will need that confidence rebuilding if we want trophies next year.
