Well, the first fact you've got wrong is that he's been here 4 years, not 5.
A second fact is that in 2 of those 4 years he got player of the season on here, a fact you conveniently seem to have forgotten.
In my opinion, his form started to dip following the howler at Anfield with the Origi goal, and became gradually worse over the next 24 months. Over that period the number and frequency of mistakes increased at the same time the good parts of his game were being eroded, culminating in his form during the early part of last season when he had become a liability to the team. But your making out that he's been playing to those very poor standards throughout his "5" year term here, which is not, in fact, a fact, but merely pure drivel.
Here's a couple of my post from the feeding frenzy period last Autumn.
There were a small number of posters on here regularly defending Jordan during this period, and I regret that I wasn't one of them. But at the same time I didn't join in the frenzy because I genuinely believed a good keeper was still in there, it was just his head that was wrong and needed sorting out. I'm glad to say that, for a change, I was proved right. the club brought in a specialist and Jordan returned after his short "injury break" a completely different player. I think the Anfield derby, in which he was excellent, also killed off a few demons.
So the third fact I'll present to you Dave is that for the majority of this calendar year he's been one of the best keepers in the Premier and he's carried that form into the Euro's where he compared favourably with some of the best keepers in the world.
The key to Jordan going forward is keeping his head straight, and if we can do that there's no reason why he can't be our number 1 keeper for years to come.
