I dont think we will see Mascherano and Alonso play to much together in the middle, not as a midfield four anyway to similar.
Do think he will go on to be a great signing for us though, i hear Rafas already looking into sorting a longer deal ( no secret to be fair ), you could see the guys class in the second half, you cant hide class, and more importantly for a player who hasnt played for over six months he worked hard and looked stong.But it is a specialist position and i think Alonso will get the nod.
Not bad having two of the best in that position in are side though is it? add to that Steve and Momo, with better wingers we would be top.
Anyway 2-1
