Well, in the article above, Roxburgh described Wright-Phillips as a guy who can play up top or play wide and he described Stachnik as a guy who would play more in an advanced mid type of role.
As for the DP situation:
“We discussed the whole subject, but we haven’t got any specific target,” said Roxburgh. “We had some names to discuss, but we don’t have one at this moment in time that we feel will be a solution for us because you’ve got to take everything [into account]: Are they available? Would they want to come here? How much does it cost? Is it appropriate for our team? Could he blend in?
“Right now, I don’t think we’ll be doing any business like that certainly in the coming few weeks. It’s wide open over the summer period in Europe and so we don’t have to rush to it.”
Basically it's obvious guys like Benayoun are available, it's just that they don't think someone like him fits extremely well, or perhaps is good enough. Gonna be interesting if someone shakes loose later in the process. There are always guys. Cahill I'm pretty sure came along later in the game last year.
It will always, almost certainly, be a late-in-the-game situation for a DP coming to MLS. Unless its a huge deal like Henry, done well in advance, almost any player will not have MLS has his only option, so the negotiations will go to the very end of the window in order to get the best possible deal.
