if we keep playing 4-3-1-2 next year, then momo should go. if we play something with 2 players on the center like 4-2-3-1 then we must stay. we should first define our new system and then sell/buy players not the opposite way...
for example if we play 4-2-3-1 next year, i will be very happy with melo, momo, marchisio and poulsen for the center...
