several players in that camp- Torres at Chelsea for example and Carroll at Liverpool. There was the guy at Man U a season or two ago whos name escapes me, but he went to Chelsea and didn't do much there. Cost a load of money though, all of them with very little return. We have had our share too. Trying to think of one that we had the least return on, Styvar would be a good start.
Some of us don't make a big show about it or use it as a stick to beat the club with when it is very clear they may well of made the same mistake themselves..
