Is that the most blatant free-kick of the season?

Granit Xhaka has his arms all over Marko Grujic and it's enough for Kevin Friend to reach for his top pocket.

All over! Stoke have done it and beaten last season's finalists Aston Villa to reach the quarter-finals.

A superb performance and result for the Championship side.

I've lost count of the number of times Diogo Jota has been fouled. He's come under close scrutiny from Arsenal's players. Jota wins his side another free-kick after Dani Ceballos goes in hard.

Oooh, free kick awarded to Aston Villa right on the edge of the Stoke area. Jota steps up... but his ball in is well headed away.

Free-kick to Liverpool drops into Arsenal's penalty area and Marko Grujic heads into an empty Kop.

Dean Smith nervously glances at his watch as we enter the first of four minutes added on.

Stoke have dropped back to try and defend their slender lead. Nervous times for the Championship side.

A second half classic coming up!

Liverpool get us back under way.

There's a few Liverpool subs warming up at half-time.

How long before Jurgen Klopp makes changes?

The clock is ticking for Aston Villa. There's just three minutes remaining for last year's finalists to try and get a goal and give themselves a chance of staying in the competition.

Ricology: Anyone see Mo Salah tonight?! Very low profile for a surprise pick for this game. Not interested!

Arsenal have been very well organised. Liverpool almost came to life at the end of the first half and created a few opportunities. The game has opened up a little bit more and I'm expecting the same in the second half.

Just over 10 minutes remaining for Aston Villa to find an equaliser and take this game to penalties.

The hosts are marginally the better side in these closing stages but not giving Stoke too much of a headache.

Simon: The most pointless, devalued, uninteresting cup competition in the history of football (oh apart from the Nations League). Even in normal times this cup is a terrible waste of time and money and energy. But In the current world it is ridiculous this cup is happening. Most teams play their B-team. So what satisfaction do you get winning this cup? The team that progresses is the loser. Managers can’t wait to get knocked out. Unnecessary strain on squads and resources.

You ok, Simon?

Takumi Minamino should score. It's brilliant from Neco Williams. It's a good save from Leno. Minamino only has to tap it into an empty goal. It's an awkward height but Liverpool should be 1-0 ahead.

Liverpool should be ahead.

How did that not go in?

Great play by Neco Williams who sends in a cross and Diogo Jota forces a flying one-handed save from Bernd Leno.

The rebound falls to Takumi Minamino who should score but hits the woodwork.

Almost an immediate impact from substitute Ollie Watkins but the striker's effort with his first touch is tipped over by Adam Davies.

Liverpool want a penalty!

Diogo Jota goes down right on the edge of the area after a lunge by Dani Ceballos.

Free-kick says Kevin Friend.

Did I just see that?

Curtis Jones attempts to cross the ball with a 'rabona'.

Why not?

Great feet from the lively Anwar El Ghazi as he weaves through the Stoke defence but then shoots straight at Adam Davies in the Stoke goal.
