Truly, it is the case, just as it has been for other players too. If it was just about what you say, then few would have a problem with it. However, the posts, by some, have been inflammatory, unwarranted, and personal. It isn't difficult: support the players until they leave, or if they have harmed the club with their words or actions.
Here is just one post of many:
His undersized shorts, pulled down socks and ponsey haircut says everything about him. An absolute pre-madonna who is proving to make the money spent on Jo and RSC look like sale of the century. Against Watford his appalling finishing made Grealish their best defender. He even managed to block a goal bound shot. Today, he was useless yet again and his inability to miss an empty goal from 6 yards (He's a £100m player remember!) is beyond the joke. What the likes of Palmer must be thinking watching Grealish is anyone's guess!
