Interesting and contrasting views going around. Patrick at 20:30 BST said Morgan was making a case for the starting jersey. I don't think Chris agrees.

When the Lions' attack is flowing it looks really, really good.

They work it well off the line-out as Freeman breaks clear of a tackle, but Tuipulotu just can't find Aki and the ball drops forward.

The Lions' scrum is on top so far and they win a penalty just inside Argentina's half.

Smith makes some decent territory and they'll have the throw deep in the 22.

Tomas Albornoz lands the kick to put Argentina back in front by a single point.

Argentina win a penalty as Tom Curry is pinged for holding on at the ruck and the Pumas point to the posts.

Who has impressed you so far? Let us know your thoughts!

I'm sitting next to an Ireland fan who bet on Bundee Aki for first Lions try-scorer - he's thrilled! That was slick attack from the Lions backs, with both centres getting plenty of touches. They look a potent threat.

For a second it looked like James Doleman was going to send Matera to the sin-bin, but he says there was only a split second before the hit Smith and changes his mind.

A penalty only, just outside the 22, and that feels like the right decision.

It's for a collision between Pablo Matera and Fin Smith as the Lions' fly-half gathered the ball.

Santiago Carreras is met with the full force of Duhan van der Merwe as he chased a kick.

We're going to the TMO, but I don't think it's for that hit.

Tommy Freeman shows some nice feet to dance his way out of his own 22.

Would be a 10/10 on Strictly, so it would.

Despite the chalking off of two scores, that try caps off a strong opening for the Lions in terms of their attack.

Andy Farrell's side have put together some nice passages...all the more so when you consider we're talking about a team who have never, ever, played together.

Fin Smith in particular has things motoring along really nicely.

The Lions are piling the pressure on...surely a try is coming?!

Argentina were 7/1 with the bookies to win this evening, remarkable odds given their status as a Rugby Championship powerhouse.

They've given the Lions plenty to ponder in the opening quarter of an hour and have managed to cut open the hosts' defence on a number of occasions.

But lots for Andy Farrell to be encouraged about in the Lions' attack, with the giant wings Tommy Freeman and Duhan van der Merwe both menacing with the ball in hand.

It's no try.

It was pushed forward by Joel Sclavi onto the palm of Mitchell, who then pushed it forward and Tuipulotu was there to gather the rebound and cross.

That's the right call, but a second disallowed try for Andy Farrell's men.

They've a scrum in a good position now, though.

Sione Tuipulotu is over under the posts and we're going to the TMO again!

The ball definitely bobbled forwards, but was it back off an Argentine hand?
