There were a flurry of yellow cards in the first leg at Upton Park. And there's alreay been a couple of tasy challenges by the hosts on West Ham's player in the opening exchanges in Romania? Can the Hammers finish a match with 11 players?

We're under way in Romania and Holland. 

Ready to go? It's make or break for West Ham. We're almost ready for the off.

While Southampton manager Ronald Koeman limps his way to the dugout - he's hurt his achilles' tendon - brother Erwin has been talking to BT Sport.

Great scenes inside Arnhem's Gelredome. The hosts might be trailing 3-0 but the locals have turned up in force. A sea of yellow and black as both teams emerge from the tunnel.

Doniel Henry,Kyle Knoyle and Manuel Lanzini are all making their senior debuts this evening. Defender Henry, 22, is a Canadian international, who was all set to make his debut for the Hammers last season but ended up being shipped to Blackburn on loan instead. 

Knoyle is an 18-year-old full-back who has come through the legendary Hammers academy and is an England youth international. And Lanzini is an Argentine attacking midfielder, 22, who impressed in West Ham's recent friendly against Werder Bremen.

Goals by Graziano Pelle, Dusan Tadic and Shane Long have put Southampton in a strong position against Vitesse but Saints boss Ronald Koeman is not taking any chances against his former club.

Saints are away to Newcastle on Sunday but, unlike his West Ham counterpart Slaven Bilic, Koeman has brought his strongest possible side to Arnhem.

"It's crazy to think about it, to throw everything away at the start of the Europa League legs," said Koeman, when asked why he had not rested some of his players.

Fifteen minutes to kick-off in Giurgiu and Arnhem. 

It looks like a scorcher in Romania where West Ham boss Slaven Bilic is banned from the touchline following his 'dismissal' in the first leg.

Southampton and West Ham are not the only British clubs in action. Manager Derek McInnes insists there is no need for Aberdeen to go "gung-ho" as they seek to eliminate Kairat Almaty from the Europa League qualifiers.

The Dons trail 2-1 from last week's first leg in Kazakhstan, meaning a 1-0 win would take them through to the play-off round on away goals.

"You don't have to score in the early stages of the game," said McInnes.

"Ideally we will. There has to be a measured approach and intelligence as well passion."

Our colleagues in BBC Scotland will have a dedicated live text commentary on that one starting shortly.

Not quite the Beatles' Abbey Road album cover but West Ham's players did a pretty good job at trying to recreate the iconic image when they went walk about in Bucharest earlier.

Giurgiu, situated on the banks of the Danube River, is about an hour away from Romania's capital by car.

Are West Ham right to prioritise their Premier League game against Arsenal on Sunday and name a weakened side this evening?

Will Ronald Koeman be celebrating wildly if Southampton score in Arnhem? Not likely judging by this tweet the Saints boss posted on the eve of the tie.

Apparently Koeman has had a scan but is fit enough to take his place in the dugout at his former club.

In contrast to Slaven Bilic, Astra boss Marius Sumudica has named his strongest possible side after making the West Ham tie a priority over the league.

"The second leg against West Ham is all that matters now," the 44-year-old Romanian said, external after resting several players for a league game last weekend.

Slaven Bilic has only been in the West Ham job two months but he could be facing flak if his gamble to leave most of the club's first-team players behind in England fails to pay off.

Defender Carl Jenkinson and captain Kevin Nolan are the only two first team regulars in Romania ahead of West Ham's first Premier League game of the season at Arsenal on Sunday.

"I don't like the excuse, I don't see it as a problem, it is a situation and I'm trying to cope with it," said Bilic.

Have West Ham done the right thing by naming an under-strength team? Will they have a better Premier League season if they are out of the Europa League? Or should they been naming their strongest side despite Sunday's tough Premier League opener with Arsenal?
