Following Victor Valdes’ season-ending injury against Celta Vigo in last night’s La Liga encounter, Barcelona are only left with one established goalkeeper.As a result, the Catalan club are entertaining the idea of bringing a new keeper into the squad to seem through the title run-in as well as the Champions League.The Spanish Football Federation has made it clear, however, that Bara can only sign a keeper from the Spanish football league or a free agent.Sporting director Andoni Zubizarreta is now looking at a number of potential replacements, despite manager Tata Martino feeling he has adequate cover in 38-year old Pinto.One of the main candidates is Everton target Keylor Navas from Levante, who is neither cup-tied from European competition nor does the club have realistic targets of reaching Europe this season.Other candidates include Gorka Iraizoz, Claudio Bravo and Willy Caballero as the club look to sign an established goalkeeper with crucial games coming up.
