Barcelona take a narrow advantage into the home leg of their Champions League quarter-final with Manchester United after Luke Shaw turned a Luis Suarez header into his own net at Old Trafford.

The video assistant referee came to Barca's rescue after the Uruguayan was initially - and incorrectly - flagged offside when his nod back across goal went in off the defender's shoulder.

United had their chances to draw level but Diogo Dalot missed their best opportunity when he failed to direct his header on target from Marcus Rashford's fine cross.

Ole Gunnar Solskjaer's side must now beat Barcelona at the Nou Camp to progress to the semi-final, something they have never achieved.
