DM: Gaston Gil Romero is cheap (around 5m with instalments) and is great from the get go. Lucas Romero is better but costs a bit more. Other options: Kranevitter/Guido Pizarro (has italian second nationality). - Scout also: Albin Ekdal/Badu (Udinese). Or loan Thiago Neves (who you should eventually buy)
How much do you have? Kyriakos Papdopolous can cover both positions
thanks already have Gaston, but I need more of a back one to replace Arteta and Flamini
