Tahith Chong is desperate to use his pace. You can see every time he gets the ball he wants to get running at full speed.

His willingness to do the right thing, which is use that pace, is clear to see.

Yacine Brahimi takes advantage of a lapse in concentration from substitute Bryan Cristante and almost gives Porto that crucial winning goal.

He runs in behind but his mishit volley is kept out by the inside of Robin Olsen's leg. The Porto manager then slips as he tries to control the ball on the sidelines and looks like he's pulled his hammy! Poor bloke.

Is this it? No!

Really well played David de Gea as Kylian Mbappe is played through on goal, De Gea is out and in his face, forces the Frenchman wide and he slips at the vital moment. Left-back Juan Bernat picks up the pieces, under pressure, and with two men on the line he hits the base of the post.

If Mbappe keeps his feet he scores...

Tahith Chong is playing on the left wing, Marcus Rashford is up front with a knackered-looking Romelu Lukaku. Kylian Mbappe gets into the area at the other end but again his touch is a bit heavy.

PSG don't need another goal but they're not shutting off. They want a fourth on aggregate which would end it once and for all.

OGS is going for it - Tahith Chong comes on for Andreas Pereira. A proper 4-4-2 for the last 10, and why not? His side need a goal.

Tom Miszkowski: United playing like a boxer holding out for a 12th round knockout. OGS showing his tactical nous. PSG with all of the ball but no idea what to do with it, could quite easily make another mistake.

Dave Payn: Re 71 mins. He might as well go for it now. Man U in a position that would have seemed unlikely before the match.

Mikey Gear: Am calling it..Mason Greenwood comes on for Lukaku, we have a break with Rashy, and he squares it for the new Kid to get his debut goal.

PLEASE do! Oh, it's going to be Tahith Chong coming on...

DeathApeDisco: Man Utd won 2-1 with Bailly on the field and are drawing 0-0 without him. They need to win the next bit 2-1. Send Bailly back on.

Bad touch! Kylian Mbappe takes a heavy touch inside the area and that's a real let-off for Ashley Young, who was caught on the ball by Angel di Maria.

It's all getting a bit tense down there.

Leandro Paredes, who has just come on, catches Andreas Pereira and goes straight into the book.

Ashley Young's been brilliant, he's made one or two phenomenal interceptions since going back to right-back. He looks so much better there, as do Manchester United when he's in that position.

PSG 1-2 Man Utd (Agg: 3-2) - PSG going through

Porto 2-1 Roma (Agg: 3-3) - Going to extra-time.

Marcus Rashford has moved back up front alongside Romelu Lukaku. Can the visitors find that goal they need?

Porto are pushing for a winner. It's an excellent ball in from Alex Telles but Felipe's header bounces into the ground and over the bar.

At the other end, Edin Dzeko drags his shot wide of the keeper's left post.

End-to-end stuff!

Last 20. When do you go for broke if you're Ole Gunnar Solskjaer?

Ashley Young has to clear away from inside the six-yard box. Good defending.

David Freedman: United need to get some possession and move up. They still need a goal.

Dale Topley: Man Utd are going to have to throw caution to the wind at some point, they look like they’ve forgotten they need a goal.

Julian Draxler and Thilo Kehrer come off, on come Leandro Paredes and Thomas Meunier.

PSG 1-2 Man Utd (Agg: 3-2)

United break over halfway, options right and left for Romelu Lukaku but his eventual crossfield attempt is poor, underhit and tired. Easily cut out.

United's last shot was their second goal. Julian Draxler has twanged a muscle and needs some help.
