We have known this was coming for ages, of course, and it feels worse at the moment because Clark is in a decent run of form. But to be honest, such good form has been in short supply over the past couple of years, largely due to injuries, and he always looks like a player who struggles to get through a game without picking up some sort of knock. Sad as it is to see him go, it might just prove better than hanging on to him for too long.
