Evening all. It's the most wonderful time of the year.. ...yes, I know people like Christmas and all that, but come on: absolutely banging football, night after night is better than anything else the seven kingdoms have to offer, and here we are not, right in the middle of it. Ooh yeah!

Sevcik has pulled a goal back for Slavia, who trail Chelsea 4-2 on the night and 5-2 on aggregate.

"Sloppy from Mkhitaryan"; ctrl c, ctrl v.

WHAT A MISS! WHAT A SAVE! Lacazette slides a pass into space behind the Napoli defence and Mkhitaryan runs onto it, then clips a ball into the middle for Aubameyang - in the middle, on his bill, and six yards out. He makes decent contact too, looking to lift his finish, but from nowhere, Meret dives across the shot, blocking it with his body.

I think Callejon is sort of playing right-back.

Lovely from Insigne, who skirts around Maitland-Niles, looks up, and lays back to Ruiz at the edge of the box, who spanks a horrible shot way over the bar.

Carlo Ancelotti has made a change: Maksimovic is off and Mertens is on.

We go again.

The Napoli players surround the ref, I've no idea why, but they've been absolute nonsense in this tie and deserve to be almost out of it. Arsenal have been ok tonight, and so far, that's plenty good enough.

Half-time: Napoli 0-1 Arsenal (agg 0-2)

Maksimovic cuts the ball across the box and Callejon lets it go, then, from 15 yards, Zielinski applies the hammer, but Sokratis thrusts his midriff in the road.

Insigne tucks back to Zielinski, and his shot is deflected behind; Cech palms Ghoulam's corner down, and someone or other clears.

There'll be four added minutes.

Insigne digs out a cross and Milik is up above Koscielny, but can't direct his header anywhere good.

Trudat.

Arsenal v Chelsea in Baku sounds like one of the most horrible scenarios ever dreamed up by mankind.

Insigne controls the ball with his arm then, when the whistle blows, hoofs it away in a little tantrum; he's booked, but you could argue that he committed two yellow-card offences there.

Allan lifts a ball into the box and Callejon is up, right side of it. But he can only guide a tame header over the bar.

4-2 down from the first leg, Eintracht Frankfurt have pulled another one back against Benfica.

Lacazette is into this, and pulling left, he checks, then rills a clever pass through Mksimovic's legs towards the near post, but Aubameyang can't quite get to it and the ball rolls beyond the far.

Napoli don't deserve any more, really. They've made a couple of chances, but their general play has been very poor, and for a side chasing the game, they've shown no intensity whatsoever.
