MANCHESTER, England (Reuters) - Barcelona will take a 1-0 lead over Manchester United into next week's second leg of their Champions League quarter-final after a 12th-minute Luke Shaw own goal gave them victory at Old Trafford on Wednesday.
Sergio Busquets found Lionel Messi with a clever ball into the area and the Argentine carved out space on the left to deliver a lofted cross to Luis Suarez at the back post.
The Uruguayan's header deflected off the shoulder of a scrambling Shaw and beat David De Gea to give the visitors the lead and although the linesman initially flagged for offside, the goal was given after a VAR video review.
United's best chance of the first half fell to Diogo Dalot but the Portuguese made a mess of a fine Marcus Rashford cross, heading harmlessly across the goal from close-range.
Ole Gunnar Solskjaer's team had struggled to get a foothold in the game during the opening 45 minutes but they were much improved after the break, applying plenty of pressure without creating any clear chances.
Barcelona could have added a second had Suarez not fired into the side-netting from a promising position after a clever through ball from Nelson Semedo.
Barcelona have not lost at home in the Champions League since 2013.
