Hello and welcome to our LIVE coverage of the Europa League quarter-final first leg between Arsenal and Slavia Prague. Mikel Arteta’s side are 10 points off the Premier League’s top four and some way off the Europa League places, so you’d fancy they need to win this competition to have a chance of playing in Europe next season.

Double change coming up for Slavia...

Arsenal have hit the woodwork twice and missed a one-on-one now...and that last chance from Lacazette was a big one too.

Another big chance for Arsenal comes and goes and it's Lacazette again. Saka delivers a lovely ball from the right and his team-mate, on the stretch, puts the ball over the bar.

It was a massive opportunity...

Huge chance! How on earth has Lacazette not scored this?! He steals the ball on the half-way line and runs the length of the half with no one in front of him. The French striker takes his time to pick his spot - but hits the upright. Massive opportunity missed for the home side.

An hour played and still no goals. Arsenal no where near their best...time for a change?

CHANCE! Best opportunity of the game for the visitors who work the ball well to Boril, but the captain's shot is saved by the legs of Leno.

A rare poor moment from Saka, after Lacazette sets up a counter attack well he plays it to the winger but his cross is poor with the situation three on three.

Really promising driving run from Partey, who goes past a number of Slavia players but then cuts back and plays it to the opposition...it was pretty good up to that point!

Slight concern for Gabriel who is feeling his foot after a tough challenge, but he looks likely to play on, despite plenty of grimacing.

Decent attack from Slavia, who win the corner. It's taken deep to Stanciu who thumps a volley from the edge of the area which is blocked by Arsenal. No-one had picked out the Romanian, but it would have been some goal.

OFF THE WOODWORK! Willian eventually takes the resulting free-kick, after a check to see if should actually be a penalty, and the Brazilian clips the post with a brilliant effort from the right edge of the box.

Brilliant play from Saka, exchanging passes with Hector Bellerin, and the England international wins a free-kick just outside the penalty area. Zima just can't live with Saka and he's been booked.

Half-time change for Slavia sees Hromada replaced by Petr Sevcik.

We're back underway for the second half.

Elsewhere, Manchester United are 1-0 up at Granada through Marcus Rashford. Villarreal are winning 1-0 at Dinamo Kiev, moving a possible reunion closer for Arsenal and their former manager Unai Emery. Ajax lead Roma 1-0.

Saka's such a huge talent, and was definitely the most impressive player in that first half. But he also missed the best chance, putting a shot wide when one-on-one with the goalkeeper.

It's not been great, though...

That's the whistle for the break, no stoppage time. Not a lot to talk about in that half. Arsenal have been marginally the better side, but it's all been very slow. Saka had by far the best chance of the half but his shot was wide of the far post, and Holding's header forced a decent enough tip over the bar from Kolar. But you'd expect more from the home side. Very little from the visitors, who look very organised and well set up.

Really clever ball from Lacazette midway inside the Slavia half finds Saka, whose cross goes out for a corner. Boril clears well with his head and the visitors can reset again.
