Mikel Arteta takes charge of Arsenal in Europe for the first time on Thursday night.

On the back of Sunday's morale-boosting 4-0 thumping of Newcastle United, the Gunners face Olympiacos in the first leg of their Round 32 Europa League showdown.

The North London side face a tough test in Greece however.

Arsenal have won just once away from home since early December, and have claimed just four wins on the road all season.

In stark contrast, Olympiacos have lost just once on home soil - to German champions Bayern Munich - and will pose a substantial threat, even without £16million winger Daniel Podence, who joined Wolves in January.

The Karaiskakis Stadium will be rocking, and while Arteta is set to hand some of his young stars further minutes, he wants them to express themselves in what is likely to be a hostile atmosphere.

Arteta's message to his side is to be bold

“It’s part of the process,” said Arteta. “You don’t know until you expose them. They can have the best ­intentions but need to go to a stadium like here and when they make a mistake or a bad ­decision, have the courage to try again and play again.

“I want to see that in my ­players, whether they’re 17 or 35. That’s what I expect from them.

“If they keep trying, they have my full support. If they hide after that, I don’t like it. But what I’ve seen up to now, every time they play they are responding really, really well. That’s what I’m ­hoping.”

Mesut Ozil and Lucas Torreira were both missing from the travelling party on Wednesday; Ozil's wife is due to give birth while the Uruguayan has been struggling with illness.

Again set to start at left-back however is teenage starlet Bukayo Saka.

Arsenal chiefs are hoping to tie him down to a new five-year deal soon.

The England youth international, just 18, has 18 months left on his deal, worth £3,000 a week, and his potential availability has alerted other top-flight clubs.

Alexandre Lacazette, who broke his goalscoring duck against the Magpies, is set to lead the attack.

Arsenal predicted XI: Leno; Bellerin, Mustafi, Luiz, Saka; Xhaka, Willock, Ceballos; Pepe, Lacazette, Martinelli
