He probably shouldn't still be at the club.
Tim was a good goalkeeper with the ability to create the occasional moment of brilliance but also prone to a mistake.
On the whole though, he was one of the top six GK's in the country about five or six years back.
He started to decline properly after that World Cup in 2014. He probably should have gone in Summer 2014 or Summer 2015 at the latest. If he had then he would still be remembered fondly, thanked for his efforts etc.
Because he has overstayed, he is now the scourge of most of the support base. He probably won't be remembered for the good performances but for this last two years where he has been mostly awful (despite the odd moment of brilliance).
I hope he leaves in the summer, as much for his sake as our own.
