Shaw own goal hands Barca control

Manchester United have another monumental task on their hands in the Champions League after Luke Shaw's own goal gave Barcelona a 1-0 quarterfinal, first leg lead at Old Trafford.

Shaw turned Luis Suarez's header into his own net after just 12 minutes and despite being far from their best, Barca comfortably held out to edge towards a first Champions League semifinal in four years.

United produced one of the European Cup's finest ever comebacks from a 2-0 first-leg defeat at home to Paris Saint-Germain in the last 16.

However, on the ground where manager Ole Gunnar Solskjaer completed another famous fightback to win the competition as a player in 1999, United must repeat the trick at the Camp Nou in six days' time.

Much has been made of Suarez's Champions League goal drought on the road and while the Uruguayan has still not officially netted an away goal in the competition since September 2015, he had a huge hand in Barca's winner.

Lionel Messi drifted in behind the United defence and his cross hung up to the back post was headed goalwards by Suarez, the ball flicking off Shaw on its way past David de Gea.

An errant offside flag briefly threatened to spoil Suarez's delight. However, the goal was quickly given on a VAR review and the former Liverpool striker took extra glee at having the last laugh with a fist pump in front of the Stretford End.

The early goal should have settled the Spanish champions into their stride as their dominance of possession touched close to 90 percent in the opening stages.

Yet, they offered United plenty of encouragement with Sergio Busquets in particular off the pace.

Marcus Rashford shrugged off an ankle injury to start and provided by a distance United's biggest threat.

A free-kick from the England international flew just wide inside the first five minutes and he sent another dipping effort from range just over Marc-Andre ter Stegen's crossbar.

United defender Chris Smalling had said "bring it on" at the prospect of facing Messi on the eve of the game.

And he left the Argentine bloodied from the nose as he careered into an aerial challenge on the half-hour mark.

Messi was quickly back on his feet and into the heart of the action, but it was Philippe Coutinho who came closest to extending Barca's advantage before the break with a thunderous low shot that De Gea did brilliantly to repel with his feet.

Moments later United could easily have been on level terms, but the hosts' best chance of the half fell to the wrong man as Rashford picked out Diogo Dalot only for the Portuguese to completely miscue his header across goal.

Rashford, though, also failed to make proper contact with his big chance early in the second-half when Ter Stegen could only punch a cross into his path.

United enjoyed the better of the opening stages in the second half, but lacked a creative spark to open Barca up with Paul Pogba too often picking the sideways pass.

Barca boss Ernesto Valverde reacted by introducing midfielders Sergi Roberto and Arturo Vidal from the bench in order to restore to control. And as United chased in vain for an equaliser, the visitors began to create chances again in the final quarter.

Suarez fired into the side-netting before De Gea used his feet to good effect once more to deny Jordi Alba.
