A slip from Konstantinos Mavropanos gifts Morgan Rogers the ball and Villa have a two vs one.

Rogers' ball forward for Ollie Watkins is too close to Max Kilman though who makes a key interception.

Crucial that.

Graham Potter makes another change. Off goes youngster Ollie Scarles, replaced by full-back Aaron Cresswell.

So close to 3-1 Aston Villa!

They looks so good on the counter now as Jacob Ramsey strikes the ball beautifully from the edge of the box and sees his shot clatter against the post.

West Ham are starting to collapse.

With so much going on I've not been able to tell you about the three changes Aston Villa made between the two goals.

Matty Cash, Leon Bailey and Boubacar Kamara went off. On came Kosta Nedeljkovic, Jacob Ramsey and Emiliano Buendia.

It's amazing when you use the ball and pass the ball at pace.

Youri Tielemans passed the ball into Emi Beundia, he faces the play and passes to Ollie Watkins.

Watkins goes into the box and pings it across the box and Rogers is there.

That's how you play football.

A poor performance from Portsmouth and two well-taken goals from Wycombe see the League One side complete an upset and book their spot in the fourth round of the FA Cup.

It's an upset in terms of the fact Portsmouth are in the league above, but it's worth remembering the two are having very different fortunes in their respective leagues.

Wycombe were by far the better side in the first half. Neither did anything of note in the second.

Portsmouth's Terry Devlin is shown a yellow card for a foul.

Villa had dominated since half-time but have earned a slice of good fortune as it should not have been a corner in the build-up to the leveller.

Just seen the replay and West Ham are right to feel aggrieved. Boubacar Kamara's shot was not deflected and instead went straight out of play. It should have been a goal kick.

There was little in Lucas Paqueta's clash with Ezri Konsa though.

West Ham are furious with the referee. They think Villa's corner should never have been awarded.

Lucas Paqueta also went down as the cross came in but no foul was given.

Four minutes added on at the end of this one. It looks like it's Wycombe who will be heading into the fourth round.

Good play from Villa.

Corner routine from the training ground. Tyrone Mings goes to the near post and he flicks it on. Ian Maatsen hits the ball so cleanly.

Now we have a game on!

"We want a shot," chant the Portsmouth fans.

That sums up Pompey's performance this evening.

Aston Villa are going route one now, why not?

Robin Olsen pings a lovely ball over the top for Matty Cash but Ollie Watkins can't turn in his cross.

Moments later Youri Tielemans has another shot blocked, and Ian Maatsen hits an effort which Lukasz Fabianski keeps out by diving to his right.

Another Wycombe substitution. David Wheeler replaces Beryly Lubala.
