We've become so accustomed to perfection that we seem to forget that a football team requires more than just technically the very best of the best.
In fact I'd argue that as important as technique in our squad is mentality. It's the mentality that gets you the volume of points/trophies. It's the mentality that elevates Raz above the overwhelmingly vast majority of his peers. Mentality got us 100 points when the league was won weeks if not months before. Mentality gets you turning up week in week out at every single ground and playing like you're in a cup final. Look at how not just Sterling but many players have fought back from being dropped by Pep. I think we're beyond lucky to have the squad we have.
Without the 3 least technical players in the squad - Sterling, Waker, Dias - we would win nothing.
