Can't really remember what I was doing at 17 but it certainly didn't involve playing Champions League fitbaw.

Maybe on Pro Evo or that.

What a night for 17-year-old Mitchel Frame. Seventeen. Let that sink in.

And he's playing on the Champions League stage. Brilliant stuff.

Cillian Sheridan
Former Celtic striker on BBC Sportsound

I was 18 when I made my Celtic debut.

Frame is so young, he's almost too young to overthink it.

Mitchel Frame, welcome.

The youngster bursts down the left then fires in a stunning cross, but Feyenoord clear.

The Feyenoord boss has been a wee bit miffed by some of the decisions that have gone against his side this evening and he's letting the fourth official know all about it.

Not sure he's got much cause for complaint.

Swedish centre-back Lagerbielke will replace Stephen Welsh.

Luis Palma's night is over as well and he's replaced by teenager Mitchel Frame.

What a night to make your debut!

Celtic 1-0 Feyenoord

Stoppage in play as Luis Palma receives treatment for a bloody nose.

Meanwhile, Gustaf Lagerbielke is stripped.

James Forrest sends in a cross from the right and Oh gets in front of his marker.

But his feet get mixed up and his finish is all wrong.

It was a tough one.

Celtic are inviting pressure on.

Some of the passes are unnecessary and they are bringing Feyenoord on to them.

Double Celtic change as striker Oh and James Forrest replace Mikey Johnston and Kyogo.

The away crowd scream for a penalty as Mats Wieffer goes down.

Greg Taylor left a leg out there but it didn't make too much connect - if any.

It was outside the box anyway.

Celtic are just knocking the ball at the back, waiting for the opportunity to pass it forward.

They've lost that speed and zip they had at the start of the first half, but they still look comfortable on the ball.

Feyenoord are very much on top again.

Celtic just can't get a grip of the ball at present.

He can't believe he hasn't made it 2-0. Neither can I.

It was a stunning save from Justin Bijlow that denied Luis Palma not long ago.

A deflected Luka Ivanusec effort from the left loops just wide of the far post.

Could've easily nestled in that left-hand corner.

Feyenoord fly forward with bodies as Joe Hart beats away another cross.

Mats Wieffer hits the rebound but Paulo Bernardo makes a big block.

Celtic 1-0 Feyenoord

Callum McGregor is in a bit of pain after he's caught a wee bit late.

He seems to be fine to continue as Feyenoord make a triple change.

Another Feyenoord cross into the Celtic box ricochets off bodies before Joe Hart claims with relief again.

James McFadden

That's an incredible save, absolutely incredible.

I thought he would go across goal, but he reverses it to the near post and Bijlow gets his foot out to turn it round the post.

What a save that is. Wow.

Paulo Bernardo's cross the back post is touched inside by Luis Palma, who reverses a finish to the near post.

But the big right boot of Justin Bijlow turns it away from goal.
