It's been a disappointing performance by the Basel players apart from Tomas Vaclik. The keeper has done as well has he can do against a rampant Gunners side and he really takes one for the team as he stops a close-range strike by Alexis Sanchez with a, ahem, sensitive part of his body.
Into two minutes of stoppage time.

Arsenal 2-0 Basel

Arsenal are in control, so much so they can afford to do a bit of showboating as a bit of one touch passing wakes up the home fans and prompts a few oles.
Celtic 3-3 Manchester City
A change for Celtic as Patrick Roberts comes on against his parent club, replacing James Forrest.

How did he miss that!?
Arsenal haven't been quite as energetic as they were in the first half but when they turn do turn it on again it should result in the third.
Santi Cazorla feeds Theo Walcott down by the byeline and he clips it back for Alexis Sanchez, who is six yards out and dead centre of goal, but the forward shoots wide.

Napoli and PSG are out of sight now surely. The Italian side now lead 4-0 against Benfica after two goals in four minutes - an Arkadiusz Milik penalty and Dries Mertens' second of the game.
Edinson Cavani has also bagged his second of the night to make it Ludogorets 1-3 PSG. The home side missed a penalty just before Cavani scored his second to rub salt firmly into the wound.

It's a little bit desperate now and again for Celtic, but that's to be expected. They know Aguero will keep running as long as he's on the pitch, looking to get in behind. They cannot let up for a second.
