Middlesbrough manager Aitor Karanka says Victor Valdes' influence both on and off the pitch cannot be underestimated.
Aitor Karanka hailed the revival of Victor Valdes after the goalkeeper helped Middlesbrough snatch a 1-1 draw at Manchester City.
Valdes held City's incessant attack at bay, save for Sergio Aguero's 150th goal for the club, until Marten de Roon fired home a stoppage-time header to earn a point for the Teessiders at Etihad Stadium.
Having lifted the European Championship and World Cup with Spain, as well as multiple LaLiga and Champions League titles at Barcelona, Valdes has enjoyed regular action this season for the first time since a serious knee injury prematurely ended his Camp Nou career in March 2014.
