We aren't in the market for a right winger.
He would have been useful in the last couple of years, but we are going to be moving from a 4-4-2 to a 4-3-3 next season, so he wouldn't fit our system. :P
If push comes to shove Juve will just give Marchionni a million or two and tell him to fuck off.
If the report is true (and I'm far from convinced it is) it is just Marchionni trying to get more money out of the deal.
I would be astonished if those figures are accurate.
Arsenal are pretty mean, compared to the other big teams in England, when it comes to wages, so I very much doubt they are paying a squad player as much as that.
