Doubt they did seeing their side not get the win.
Regardless, it's common courtesy mate. Same way you hear artist thanking their fans for coming out and watching them. It's a sign of respect and alludes to some sort of gratitude for the support. It's crap that certain players can't even be bothered to show our club's fanbase atleast some gratitude to support them. Just shows that they don't have a connection with this club or its fanbase which sucks.
Maybe I differ, but for me, an away trip is, and always has been, much more than just the game itself, it's travelling with your mates, having a laugh in the boozer and general camaraderie. Of course, the match itself can make it one of those really memorable aways or one of those where the atmosphere on the way back is a bit more subdued, but, it's about the whole day. But you attend fully aware that it might not be your day, that's the deal, the contract if you like, so moaning when it doesn't go your way seems churlish to me.
Comparisons to the theatre or your local band are off the mark, they are completely different events, you love the music so it's almost nailed on your going to have a great time and the feedback to the performers is always going to be good. That said I've been to gigs where the crowd has been mental and you can see the band feed off it. I've also been to gigs where the audience is a bit flat and you can invariably see the effort/energy of the band suffers, but in the main your guaranteed a good time of some degree.
Personally I don't want the players to 'thank us' for attending. I chose to do that of my own free will and because I wanted to. What I do want the players to do is show their appreciation when we 'the fans' have given it our all vocally to back the team and they are genuinally appreciative of our support, but that's just me. If they don't do that then that's poor form.
Some fans mention on this thread a lack of solidarity and engagement from the players but how is that supposed to happen if players are getting slagged on forums, twitter and heaven forbid at the games themselves. You can't expect any player to feel a connection with the fans if they are getting slagged. Joe Hart is held up as a great example and I would agree but then he has very rarely suffered any abuse.
I always find it ironic how fans can moan about the badge, the catering, the manager, the players, pretty much every facet of the club, but woe betide any fan, like me, who dares to criticise the fans, they are the only thing that seem beyond reproach in many City fans eyes, but in my mind, it's time a lot of fans took a long hard look in the mirror...
