Visiting Barcelona beat Man Utd 1-0 in the first leg of Champions League quarter-final on Wednesday night after a first-half own goal by Luke Shaw at Old Trafford.

Luis Suarez’s 12th-minute back-post header was deflected past David de Gea by United left-back Shaw.

Manchester United must now produce another unlikely Champions League comeback during next week’s return leg to keep their hopes alive.

Elsewhere on the night, Cristiano Ronaldo secured an away goal for Juventus as they drew the first leg of their Champions League quarter-final against Ajax.

Ronaldo, who has won the competition five times, netted his 125th Champions League goal just before half-time with a diving header following Joao Cancelo’s cross.

The goal had come against the run of play, but the hosts equalised within a minute of the second half starting, through David Neres’ fine curling effort from 15 yards.

Both teams had late chances with Ajax’s Jurgen Ekkelenkamp having a shot saved before Juventus substitute Douglas Costa hit the post.

But neither side could grab a winner and they meet in the second leg in Turin on Tuesday, 16 April.

The winners of the tie face either Tottenham or Manchester City in the semi-finals, with Mauricio Pochettino’s side holding a 1-0 advantage after Tuesday’s first leg in London.
