Agree regarding Maddison. Every transfer is a risk, his would be a bigger risk than most, and there is no guarantee that we'd be able to get the best out of him. But if his wage demands are favourable, I'd be willing to give him a go. His best football is undoubtedly in the number 10 role, but at Peterborough he was at times just as effective when out wide (at Hull he was poor out wide, but he barely had any games).
You'd hope that maybe this summer has been a bit of a wake up call for him regarding his demands, as it's not like he has a queue of suitors at his door.
Also think you're right in terms of us being in for Roberts. If we get him, I cannot see us shelling out on a 2nd similar player.
I'm not usually in favour of going for players who have reputations for attitude problems, leopards and spots and all that. But I do think with a team as functional and as rigid as ours, Marcus Maddison wouldn't be the worst signing in the world, assuming the wages were at the lower end of the scale. As an option off the bench, even having an impact a handful of times over the season could make a difference.
However, I'd imagine that if we're still in for Roberts, he's probably going to fill that same spot in the squad.
From everything I've heard/seen he does seem to have a massively over inflated opinion of himself. I'm sure in January, there was talk in the press that he'd priced himself out of a move to the championship.
I found this YouTube video (I'll post the link below) of the Peterborough chairman talking about their January window, of which Maddison is discussed at length. Very much backs up that Maddison has priced himself out of moves and has a high opinion of himself. His agents also seem like tools too.
In the video he also mentions that 7 clubs had interest in Toney and another 7 had interest, but couldn't do a deal until the summer due to FFP. Wonder if we were one of those. He also mentions 1 club making 4 bids in January, and he mentions he "loves their model", which in my opinion is Brentford.
