Iran Press/Europe: Barca looked set for a damaging stalemate at Camp Nou after Atletico's defeat by Sevilla on Saturday but Valladolid had Oscar Plano harshly sent off with 12 minutes left and Dembele snatched a 1-0 victory.
His strike could prove a crucial moment in the Spanish title race, with Barca now breathing down Atletico's necks ahead of Saturday's meeting with Real Madrid, who are three points off the top.
If Ronald Koeman's men win at Valdebebas, they will claim first place for 24 hours at least, before a depleted and deflated Atletico play away at Real Betis on Sunday.
