Ole Gunnar Solskjaer was frustrated by the way Manchester United blew victory at the death and allowed AC Milan to grab a potentially crucial away goal in this Europa League tie.

Despite being second best for much of Thursday’s last-16 first leg, the Red Devils looked set to head to San Siro next week in the driving seat thanks to teenage substitute Amad Diallo’s first goal for the club.

The 18-year-old became the club’s fourth youngest European goalscorer thanks to his superb, improvised header – a fine effort that was cancelled out deep in stoppage time.

“We are working to grow and bring Milan back where we belong,” said the Rossoneri boss, who was annoyed to see Franck Kessie’s early opener ruled out for handball.

“These are the best games in that sense, so I was happy to face a team like United.

“It was a great performance and a great result, but we need another perfect performance to qualify against such a strong team.

“I keep repeating to my players that I’m not coaching a normal group. This an extraordinary group, the lads always give their 100 per cent in every game, they are just incredible.

“Before the game we would have been very happy with a 1-1 draw. Tonight we know that we could have earned even more after this performance.”
