Hello and welcome to LIVE updates of the FA Cup semi final between Arsenal and holders Manchester City at Wembley. Kick off 19.45 BST.

De Bruyne hits his shot from a half-cleared corner into the ground and Sterling nods it over. The flag was up, so it wouldn't have counted.

The Gunners push forward in the hope of snaring another. A flowing move from right to left ends with Maitland -Niles overlapping dangerously, but his cross is far too close to Ederson.

An important few minutes ahead for Arsenal. Arteta will be desperate to take a lead in at the break.

Eat, sleep and protect the ball.

Arsenal enjoying some good possession. The game-plan has worked well so far. Soak up and counter. The players know their roles and are taking advantage of a real drop off from their opponents. The blueprint was the Liverpool match. Guardiola may have some thinking to do at the interval.

Another defensive error - but this time from City. Ederson's pass is seized upon by the Gunners. It's fed to Aubameyang with his back to the keeper, but the forward's lay off can't find a teammate. Let off for the Citizens.

More dodgy play at the back from the Gunners when in possession though. Bellerin plays it straight to Jesus, who lays it back to De Bruyne. The Belgian arrives on cue but his 20-yard pile-driver is brilliantly blocked.

City beginning to turn the screw again. Mendy hurdles a challenge on the run down the left. He drills it into the middle, but once again it's an Arsenal shirt in the way.

Drinks break!

VIDEO: Auba strikes first blood.

Arsenal are growing in confidence. City needing a response. They were like a smothering blanket early on, but the Gunners have slowly settled into it.

GOAL! Aubameyang slides in at the far post to flash Pepe's wonderful right-wing cross into the opposite corner.

SAVE! Aubameyang is left in acres to turn on to Luiz's pass and size up a clear run at Ederson. He pulls the trigger but fires straight at the City keeper, who makes a big save.

DID YOU KNOW? Arsenal have knocked out the holders of the FA Cup each of the past five times they've faced them. This is their first showdown with the previous year's winners since the 2014 semi-final against Wigan Athletic.
