Poor defending from Rennes, both the keeper and defender should be doing everything to get in the way of that header from Maitland-Niles, instead they just dangle a couple of legs at it. Soft, very soft.

Slavia Prague are 3-2 up against Sevilla on aggregate after Michael Ngadeu-Ngadjui gives them the lead at home.
The Spanish side need two goals now because of the away goal rule.
Arsenal 2-0 Rennes (3-3 agg)
Rennes defender Mexer is booked for catching Alexandre Lacazette. Bit of a harsh yellow.
Ainsley Maitland-Niles
Arsenal lead on away goals. Pierre-Emerick Aubameyang is probably offside in the build-up but no VAR in the Europa League.
Aubameyang passes to Aaron Ramsey, who plays the ball back to the striker. Auba isn't expecting it so has stopped but then suddenly races towards the ball - from an offside position - and crosses it for Ainsley Maitland-Niles at the back post.
But it counts.
Dynamo Kiev 0-5 Chelsea (0-8 agg)
Chelsea manager Maurizio Sarri speaking to BT Sport: "We started very well. We wanted to start in this way.
"We scored after five minutes which was a very difficult situation for the opponents. We played a wonderful first half and managed the game in the second half."
On Ruben Loftus-Cheek: "He did very well. He is improving in the last month. He has been able to train after the problem with the back. He had a wonderful match and I'm really happy he could play for 90 minutes.
"His potential as a player is very, very, high. Physically, technically and tactically he is improving, he can become one of the best midfielders not only in England but in Europe."
Arsenal 1-0 Rennes (2-3 agg)
Arsenal are tearing Rennes apart at will. Pierre-Emerick Aubameyang sends Sead Kolasinac away on the overlap and his dangerous low cross is just cleared.
Arsenal 1-0 Rennes (2-3 agg)
That was Pierre-Emerick Aubameyang's 31st goal for Arsenal in only 53 appearances. A fine striker.

Inter Milan 0-1 Eintracht Frankfurt (0-1 agg)
Inter Milan out as things stand as Luka Jovic gives Eintracht Frankfurt the lead at the San Siro. Inter would need two to go through now.
Arsenal 0-0 Rennes (1-3 agg)
They'd had a chance just before that when Aaron Ramsey played a brilliant pass over the top for Alexandre Lacazette but Rennes keeper Tomas Koubek rushed out of his box to deny him.
Arsenal 1-0 Rennes (2-3 agg)
Arsenal only need one more goal now to go through on away goals.
Pierre-Emerick Aubameyang
Here we go. Good right wing play by Ainsley Maitland-Niles, who then cuts inside and finds Aaron Ramsey. The Welshman rolls the ball across the six-yard box for Pierre-Emerick Aubameyang to tap home.
Arsenal 0-0 Rennes (1-3 agg)
Rennes have an early half-chance but Hamari Traore shoots well wide from distance. If they were to score, then Arsenal would need three to force extra time.
Arsenal 0-0 Rennes (1-3 agg)
Flares going off behind one of the goals. The smoke is all over Petr Cech's penalty area.
Arsenal 0-0 Rennes (1-3 agg)
Under way. Arsenal need to score twice at least to go through.
Since the Europa League was rebranded in 2009-10, only one side have progressed to the next round after losing 3-1 in the first leg of a knockout tie - Fulham against Juventus in 2009-10.
That's right youngsters, Clint Dempsey scored a dreamy chipped winner as the Cottagers thrashed the Old Lady 4-1 at Craven Cottage to progress to the quarter-finals.
There are a few big teams in action in the 20:00 GMT games.
Inter Milan are at home to Eintracht Frankfurt, having drawn 0-0 in Germany. Sevilla take their 2-2 draw to Slavia Prague - meaning they need to score or they'll be out on away goals.
Villarreal are looking in good shape, at home to Zenit St Petersburg, having won 3-1 in Russia. The other game sees Benfica host Dinamo Zagreb. The Croats won their home leg 1-0.
Steady on now Alistair.
