People who don't know anything keep going on about his attitude but as Duffman, Newy and JM 14 say above he doesn't seem to had any problems the last couple of years.
That's the point though isn't it, and they do have a point, and his attitude is just a piece of the puzzle.
He had half a good season in the Champo, which was 20-21, and thought he was a billy big balls, then the last 1.5 years he's not even played, so he's had to wind his neck in. It spoke volumes when Forrest were not that interested (when they had the money) and Spence not even in that interested in going there, and Spurs manager didn't even want him, and that was before a ball was kicked in the prem.
So he either can't cut it, and has a better attitude than it appeared, which means he's not a great deal (for a prem club), or he can half cut it and doesn't appear to have a great attitude, so he's not a great deal then either. There's no proof he has the ability or a good attitude. Leeds have no risk, so it's worth a punt for them.
He's back in the Champo now for Leeds, which is precisely where he was two years ago (not playing PL, never mind CL), at a time when he should ahve developed the most, and he's also had a pretty bad injury too, which lessens his future chances of being decent, if anything, which means a questionable attitude is an even bigger problem for punters. It's also worth noting he got his injury at Rennes (Championship level), but this was whilst he was largely an unused substitute.
He's 23 now, and his level looks to be mid champo or as a lesser player in a high tier championship side, which is where most of us thought he was, and where most us thought his ceiling was, even more so if his attitude was a bit dodgy.
Like I said back then, we've had Spurs pants down getting £10m for him, especially when we have Jones, and they thought they were having our pants down with the £10m of addons we were never going to see, and if they were realised as a small chance then they wouldn't have been bothered.
We just need to forget about him, he wasn't good for us, wasn't great for anyone else (they had far better in their sides), and we got good money for him, even without the addons. He's not going to be anything special, there's too many boxes he doesn't tick.
Would I have him in our side now, if his attitude was ok? Probably, as our side is weaker than it was, but we could do with a right back, but we don't really need a right wing back. I would still rather have £10m though, every day of the week. In fact I'd rather have £5m. We spent £2m on Bangura and Engel combined (both left backs I appreciate), and there's nothing suggesting Spence will be better than either of those.
