I can see why you wouldn't realise if you didn't support Chelsea, but Torres got pretty much constant support from the fans throughout his time with us. We were disappointed sure, but no one ever gave up hope on him. Even in his last season, fans were still singing his name and saying this might be it, this might be when he turned it around for him. In terms of support from the club, no other striker could have struggled for so long and have still found himself in with a good shout at starting. The club isn't stupid, we didn't buy backup strikers for years for no reason, we did it because there was always a faith he could come good. One of the big reasons why Carlo got the sack was because it was believed he wasn't able to get the best out of Torres. It's why Roman chose to bring one of the fans' most hated managers in to fix him.
One silly banner doesn't change that, in the same way that one set of Suarez t-shirts doesn't mean your entire club and fanbase is completely delusional.
