Barcelona are rumored to be signing Inigo Martinez in the near future. This player is a free transfer player. Apart from that, news regarding Messi back to Barcelona become a headline once again. Although I think Messi is also willing to return to Spain, the financial problems facing Barcelona will prevent this from happening. However, Messi will not be willing to aggree with low salary offer, considering Al-Hilal is waiting for him with a bigger salary. Unless Messi is satisfied with the money he own, salary shouldn't be a problem if he can return to Barcelona.
Messi seem willing to rejoin Barcelona this summer and it us only a matter of time before Barcelona begin steps to make Messi a Barcelona player again. Talking about the money, Messi had taken a pay-cut before to remain at the club, I'm confident he can make that sacrifice again for Barcelona been fully aware of the conditions of the club.
