All free agents that could be of some use should be considered seriously. Badelj, Meyer and Asamoah could really be usable for us.
We desperately need totall footballers in midfield, technical and complete, but, there are few of them, and they are expensive, same could be told for CF's.
4-2-3-1 could be way to go. With 2 good wingers and one CAM I would gladly accept lower quality CF, even Bacca back should give us decent amount of goals with good setup behind him, same goes for Cutrone who could be ideal for that system, Hakan also.
Reina
Conti---Leo---Roma---RR
Badelj---Biglia
Thauvin(Pavon)---Pastore---F.Anderson(Deulofeu)
Bacca
Bench: New GK(even Gabriel)
Calabria, Mussa, Zapata, new LB (Asamoah would be usefull)
Loca, Kessie, Meyer
Suso, Hakan, Bona( or let's say Bernard if Bonna is sold)
Cutrone
4-3-3 and 4-3-2-1 also options with this group.
Ultimately Aguero would come instead of Bacca, but that would be dream.
Donna, Silva, Kalinic should fetch us some money for transfers.
