I think we should cut Parrett a bit of slack here.
He may not have set the world alight when he was last here but, maybe, we expected far too much from him? He was a young player sent out on loan by his club to gain a bit of experience, get battle-hardened and toughened up a bit and we expected him to be akin to the next Glenn Hoddle from the off. His move was never likely to be a success and wasn't. Irrespective of whether or not he has anything like enough ability to become the next Hoddle, or even the next Vinny Samways, being thrown into a struggling side where the best players are being sold around him, players' wages were as likely not to paid as they were to be paid and all of the turmoil that went with it would have tested anybody and a callow youth was always likely to come up short.
Now he's a couple of years older, presumably a couple of years stronger and, hopefully, a couple of years wiser than he was and you don't get signed up by a club like Spurs if there's nothing much there to start with.
If he signs for us then Sheridan obviously rates him, just as Peter Reid did before him, and the chances of both of them fancying a player who turns out to be a duffer are slim.
Not only will he have more chance of being a success now that the club is, in comparison to back then, stabilised but he'll be playing at a lower level too. I say give him a chance because if we write him off before he's started and give him loads of stick when he does then he will, almost certainly, fail and all that will ultimately provide is the chance to say "told you so" and, personally speaking, I'd rather not have that satisfaction.
I'd be more concerned if he didn't sign. What would that tell us about the club?
