Yet, the custodian held his ground well and earned another clean sheet.Oscar Mingueza - 6/10Not the best night for the burgeoning Spaniard, who struggled to cope with Valladolid's pace on the break and didn't attempt a single tackle all night.Frenkie de Jong - 7/10He was solid defensively when Valladolid were on the front foot, but his best moments came when he stepped into the midfield, giving their defense some real cause of concern and also put in the cross which culminated in Dembele's late-winner.Clement Lenglet - 7/10Lenglet played a big role in keeping Valladolid at bay despite their attacking flair, making six clearances on the night to safeguard his net, most noteably denying Sergi Guardiola with a fantactic headed clearance in the fifth minute.Sergino Dest - 6/10He was largely ineffective when surging forward, especially in the first-half, unable to deliver anything of note to his attacking colleagues. Dest was also caught out on the break but found his feet when Barcelona switched to a back-four.Sergio Busquets - 6/10As always, the veteran midfielder kept the ball moving, but couldn't quite break down Valladolid. His off-the-ball pressing resulted in three ball recoveries too.Pedri - 7/10Pedri was at his industrious self again and heavily involved in Barca's attacking plays. He even stung Masip's hands with a powerful effort in the second-half.Jordi Alba - 7/10He fulfilled his defensive duties with elan, even tracking back whenever needed, but also made his presence felt in the attacking areas with lovely deliveries, including one key pass.Lionel Messi - 7/10The heartbeat of the side once again tonight, Messi kept the attacking juices flowing with his wonderful throughballs, whilst also attempting a few good shots himself. He laid five key passes in the game, including that sublime one to release Dembele who then fired straight at Masip.Leo Messi's family is in the building as Barcelona present him with a signed 2004-05 jersey to celebrate breaking the club's appearance record 🤗(🎥 via @FCBarcelona)pic.twitter.com/ud11q7ZfEC— B/R Football (@brfootball) April 5, 2021Antoine Griezmann - 7/10Lot of running and getting between the lines from the Frenchman, though never really a direct threat, besides that one moment when he fired his header just wide off the post from a few yards out.Ousmane Dembele - 8/10Dembele huffed and puffed all night, struggling to finish off a couple of good chances, but then slotted home the 90th minute winner at the near post to rescue all three points. His fine season continues with another massive contribution.Ousmane Dembélé’s game by numbers vs. Real Valladolid:82% pass accuracy 6 shots [3 on target]6 attempted take-ons 4 successful take-ons 2 chances created 2 fouls won1 goal Secured a potentially huge win with a late volley. 🇫🇷 pic.twitter.com/eCOrJSmWgk— Statman Dave (@StatmanDave) April 5, 2021SubstitutesRonald Araujo - 7/10He inadvertently flicked on De Jong's cross onto the path of Dembele to claim the assist for his winning goal.Francisco Trincao - 6/10Trincao made a few good runs down the right flank but was never a direct threat.Martin Braithwaite - 6/10The Dane produced a smart flick inside the area to play on Messi and then went into the books for catching Nacho on the loose arm.Ilaix Moriba - 6/10The youngster saw a headed effort just wide of target.
