Whether we think it/Sing it, Klopp will keep the players grounded and they will take nothing for granted, especially after their experience last season of going clear and losing the PL to City, they know City's potential to close them down.
So why sing a different tune compared to what the players and Klopp are doing? Shouldn't we show some solidarity? By all means be cheerful, positive, defiant... but behaving as if it's done and dusted is unnecessary. Puts Klopp and players in an awkward situation as they have to answer questions about what the fans are singing.
It would be best if we were all singing from the same song sheet, i.e. we're positive, we're confident, we're enjoying the ride, we know what we want and we hope we'll achieve it... but in the meantime we're not taking anything for granted and are just focussed on the next game.
