Ousmane Dembele volleyed in a 90th-minute winner against Real Valladolid on Monday to fire Barcelona to within a point of Atletico Madrid ahead of next weekend's Clasico in La Liga. 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. They will have to play better after being frustrated by a determined Valladolid side, with Lionel Messi delivering some firm words to his team-mates in the tunnel at half-time. "We have to step it up a gear, we have to play with more rhythm," Messi said. "If not it's going to get complicated for us." It might have been more complicated had Plano not been shown a red card in the 78th minute, his hack on Dembele from behind giving Barca a crucial advantage for the final stages. "We struggled in the first half, to create scoring opportunities in attack, and also at the back, our pressing was not very good," said Koeman.
