This! i said to a mate after the game on the weekend, i bet the fans singing the "are you gonna believe us" song has got into the players heads and they have been complacent
We as fans also need to take one game at a time, sing when we've won it
I don't personally have an issue with the song. I was brought up on that and similar songs and they often got sung throughout the season. Plenty of other clubs in the mix at the top end of the table would sing it too. It went out of fashion when we were so far away from challenging, but now we are up there again I don't have a problem with it myself. Also, if a fanbase can't sing it when 22 points ahead with three quarters of the season gone, when can they?
Others may disagree, and that's perfectly fine, but I don't think the song has led to any complacency in the players themselves. I think other factors are at work there. The whole world and his dog have been making out the title has been over for ages. It's said all over the media, said within the sport, said pretty much everywhere really. I think that's more likely to seep into the minds, even if only subconsciously, of the players than any song that might get sung, although I acknowledge that if that seed is already in there, the singing of the song does add to the narrative in a small way.
I've never bought into the idea that the title is done. Things are only done once the hard work has got you over the finish line, and never before. I'm sure it will be done, but there is a lot of hard work to be put in before it is. That's for the manager and players to implement though and, at this stage, I think it's ok for fans to sing what they like really.
I do think these days many people fret over how things might look. Not only in football, of course. You get people on anti-social media suggesting it's somehow arrogant to sing "we're gonna win the league" yet it's lost on them that it's a traditional football song that goes back many decades. It often saw fans with egg on their faces too. I remember fans singing it only for the opposition to stick one straight into the net, quickly shutting everyone up. Suppose what I'm saying it that these days people often take innocent things far too seriously and out of context.
