Forums and social media have given fans a voice that they never previously had. As in all walks of life, some people are knowledgeable, some people are emotive, some are optimistic, and some are thoughtful; some are not.
Personally, I think that football is, generally speaking, cyclical, and this team is trying to manage very high expectations, in the social media age, with a number of players that can no longer deliver the level of intensity demanded when a top-tier team plays twice a week at the highest levels. At the same time, we are also trying to integrate a brand new style of play. Some fans, who have become very used to high levels of success, are very demanding of instant results and do not have any patience with new players who take time to settle in. Some fans who have been used to periods of relative failure are less demanding and get frustrated with the other fans. All will say it as they see it and have a platform to do so.
