Dumfries teed up Marcus Thuram for a flashy finish after 30 seconds – the fastest goal in a Champions League semi-final – then the Dutchman acrobatically doubled the Serie A champions’ lead.

Yamal got the LaLiga leaders back into it with a candidate for goal of the season on the 17-year-old’s 100th Barcelona appearance and Ferran Torres levelled from six yards to end a riveting first half.

"Inter defended better than in the first half and didn't give up on attacking, taking advantage of set pieces.

“The Nerazzurri managed to limit Yamal in the second half. The result leaves everything in the balance; the second leg will be similar.

As things stand after the first legs Paris Saint-Germain are in the best position following their 1-0 win over Arsenal at the Emirates Stadium.

Barcelona and Inter Milan are locked in a beautiful draw at 3-3 and either side can make it through to the final.

Steve McManaman was asked how Inter Milan will feel after that match and said:

“It is strange. Relief probably.

“Lautaro Martinez went off, they got a goal disallowed because of a toe nail.

“They will be feeling different emotions, but really they should be thrilled to bits.”

The former Real Madrid winger told TNT Sports: “It had everything.

“It showed how frail Barcelona are defensively, but going forward they are electric.”

Lamine Yamal has received a top with 100 on the back and his teammates gather for a picture.

He made his 100th appearance for Barcelona this evening.

The former Manchester United midfielder said: “Lamine Yamal is so special.

“Remarkable to watch him. He makes everything look so easy.

“The only way Inter Milan could stop him was with three to four defenders.”

The TNT Sports pundit said: "I love the new format and tonight was just special.

“It was special to be here and watch those two teams. We were treated to some unbelievable football this evening.

“It was a joy and a privilege to be here."

90+3 mins: A fantastic match comes to a close with both teams locked in a high scoring draw.

Inter Milan twice went ahead and were reined back in by their hosts.

The stage is set perfectly for next week’s second leg when the Serie A side seek to get themselves into the Champions League final.
