Jorginho nearly frees Willian down the right wing with a lovely clipped ball over the top but it's a few yards too heavy and the chance has gone. Chelsea then attack down the left wing...

The old 'it's only half-time' chat...

Napoli are second favourites with the bookies for the Europa League behind only Chelsea, whose fans are encouraging them to break down a packed Kiev backline. They win a corner.

Arsenal

Arsenal manager Unai Emery on Arsenal's 3-1 defeat in France:

We controlled the first 40 minutes and scored and this is the first target but after the red card we cannot control it.

When we were 2-1 down it is difficult to have a better result. We wanted to hold the result but Rennes won the first 90 minutes but now we have another 90 minutes at home in front of our supporters and we want to be positive, it will be 11 v 11 again.

Goals in the other two games - Arkadiusz Milik has put Lazio 1-0 up against Red Bull Salzburg, with Rodrigo firing Valencia into a 1-0 lead against Krasnodar.

Not the most exciting 10 minutes we've seen this midweek. It's a flat, quiet atmosphere at the moment.

That's a real lunge on Davide Zappacosta and an early booking for Volodymyr Shepelev. Load the box...

Three Dynamo players are yet to have a touch.

Dominant start from Chelsea, popping the ball about with their usual style. No shots on goal yet.

David Luiz to Pedro, we've seen that before. It's a beast of a long ball over the top, Pedro's touch is a dream and Chelsea win the corner.

Under way!

N'Golo Kante is not playing tonight so that should hopefully mean that nobody tweets in mentioning where he should or shouldn't be playing in the Chelsea midfield. The most boring football chat of the season, and that's saying something.

Andriy Shevchenko - by the way - is at tonight's game.

Mark Davies: So Man Utd and Arsenal go to France to play in Europe. One plays a super rich mega-team who is a mile clear in the League and wins and the other plays a never done anything, mid-table team and loses. Who's in the best place?

Here come the sides at the Bridge...

Good win tonight for Villarreal, who beat Zenit St Petersburg 3-1 in Russia. Dinamo Zagreb claimed a narrow 1-0 victory at home to Benfica.

Sevilla drew 2-2 at home with Slavia Prague, with Eintracht Frankfurt and Inter Milan playing out a 0-0er.

In the late games, Napoli host Red Bull Salzburg and Valencia take on Krasnodar.

Chelsea

A pretty Europa Leaguey, but strong, looking line-up from Chelsea. Six changes from their Premier League win over Fulham. Olivier Giroud, Pedro, Davide Zappacosta, David Luiz, Marcos Alonso and Mateo Kovacic are all in.

Kepa starts in goal, Eden Hazard is on the bench.

Chelsea: Kepa, Alonso, Christensen, Luiz, Zappacosta, Jorginho, Barkley, Pedro, Kovacic, Willian, Giroud.

Dynamo Kiev make only one change - enforced - from their previous league game. Youngster Nazariy Rusyn is in for the injured Fran Sol up front.

Dynamo Kiev: Boyko, Sydorchuk, Shepeliev, Shaparenko, Tsygankov, Mykolenko, Burda, Buyalskiy, Shabanov, Rusyn, Kędziora.

And let's have a reminder of who is playing tonight...

Chelsea manager Maurizio Sarri says his players are "physically and mentally tired" before their Europa League last-16 first leg against Dynamo Kiev.

The game against the Ukrainian side will be Chelsea's seventh in 18 days, a run that included extra time in the Carabao Cup final with Manchester City.

It is a schedule that the former Napoli boss believes puts English clubs at a disadvantage in European competitions.

"The last week was very hard for us. We need to rest some players," said Sarri.

"We have played six, seven, eight matches more than other European teams [this season], which means two months without training. For an English team it's very difficult to be competitive in Europe in March, April."

Have a word with yourself Rezaa.
