Assuming that Umtiti gets fit again for the new year, we don't even need to bring in that expensive of a name, seeing as he would be our fourth choice anyway. Get someone cheap and Spanish to cover for Piqué, Lenglet and Umtiti and we should be off well enough for the rest of the season. I would prefer if we didn't even need to bring in anyone, but the current situation is unfortunately just not tenable with Vermaelen being made of porcelain and fortnightly falling apart. Maybe someone like Víctor Ruiz or a player with La Masia affiliation like Sergi Gómez (probably not an option, as he is a regular in Sevilla now) or Marc Muniesa. It's not like they would be playing a lot of minutes anyway.
