Barcelona's hunt for a successor to Victor Valdes is edging closer to completion, with Marc-Andre ter Stegen having reportedly completed a secret medical. The highly-rated Borussia Monchengladbach stopper has long been touted as the man Los Cules want to replace Valdes, who after more than a decade as first choice has decided to leave the club this summer. German daily Bild reports that the 21-year-old keeper has agreed to a five-year deal with the Catalan club and passed a medical.
