Juventus seems to be bargaining on Ozil. Ozil has been frozen and though the Arsenal still have option to bring him to the game, they seem to be desiring to sell him off. Arsenal has it's own problems. They had offered Ozil previously and after being rejected, they seem to have decreased the price this time. Juventus would too need some good energy for the UEFA knockouts.
Ozil could be considered replacement as long as he can be a bench player for a long time, he was a great player and Arsenal just had a problem I suppose with him, so they just do not play him, whereas he could make a difference in any team if he gets enough playing time. Obviously it would take a long time for him to get in shape, but that would be end of the season by the time he is ready, I agree that he doesn't make sense, but he is also not a null point, could be considered as a last hope.
new rumors about L. Messi
I still think with President gone, he may change his mind, maybe not now but by the time new contract negotiations come, he could be swayed to stay at least another year before he makes a decision. But playing in USA would be disservice to football community, we deserve to see more of Messi before he retires (and yes USA is semi-retirement in my eye).
