5. Bruno Soriano
Bruno Soriano is one of the oldest and a veteran of Spanish club Villareal. He captains the club at 30 years old, however, it seems that his team is acquiring younger players. Villareal acquired Sergio Asenjo(25), Denis Cheryshev(23) and Gerard Moreno(22) as part of their “remodeling” of the team.
This may not directly affect Soriano, because he is still a commanding presence in midfield, but he would definitely do well in Barcelona, who have done well with their older midfielders like Xavi. If Xavi were to leave Barcelona, which seems unlikely, Soriano would be a good replacement, because of his no nonsense attitude. If Xavi, a central defender, stays, he may pair up well with Soriano who typically plays defensive midfield.
