Arsenal news: Arsene Wenger warns Champions League clash with Olympiacos is a

However, the focus is now back on Champions League football and the upcoming clash with Olympiakos is crucial if the Gunners want to qualify for the knockout stages, after they lost their opening match against Dinamo Zagreb.

Arsenal will be without Mathieu Flamini and Mikel Arteta – both picked up muscle problems in the trip to Leicester – while Olivier Giroud is suspended.

Wenger’s side are now just three points behind Premier League leaders Manchester United, who they host next Sunday.

Arsenal have reignited their season after a rather slow start and the win over the weekend propelled them into fourth place on 13 points, level with third-placed West Ham.

“A second year without us being successful and you could come to a conclusion of, “yes, there is something we have to analyse deeply”, but I don’t believe so at the moment”.

Olympiakos come into the tie with a squad relatively unknown in the English game. It is more about what happens before.

Arsenal will be desperate to continue their recent good form in their last two games although they can not afford to underestimate another weaker side in European competition after the embarrassment they suffered in Croatia.

“We need to make sure we have a good performance at home especially and make a statement in the Champions League“.

Arsenal manager Arsene Wenger has admitted that Tuesday’s Champions League group match against Olympiacos at the Emirates is a “must-win” game.

Alexis Sanchez got off the mark for the season with a hat-trick at the King Power Stadium, with Theo Walcott also on target.

“He is one of the most passionate players I know”, said the Arsenal midfielder.
