Arsenal

If Arsenal do lose tonight, it will be their 50th defeat in the Champions League; only three sides have already reached that milestone (Porto, Galatasaray and Olympiakos).

Joseph Maxwell: Could Arsenal win Premier League or Champions League with a player transfer policy that smacks of non-league philosophy?

Cheddar Football: Let's purposely get eliminated from club football's holy grail & take a punt at just happening to chance upon winning the title.

Chelsea

Jose Mourinho says the pitch in Haifa "is really bad." He says he expects a tough game on "a heavy, slow pitch."

Arsenal

Arsenal manager Arsene Wenger has been speaking before his side's game against Olympiakos.

On his team selection: "I've put players who know their positions in those positions and I didn’t want to be too adventurous with Aaron Ramsey after 31 days out."

On keeping an ear on Bayern v Olympiakos: "I won’t need any special information about what is happening in Munich but I will be told anyway."

In the build-up to tonight's game, Arsene Wenger criticised Uefa's drug regulations, saying current rules "basically accept doping".

The Arsenal manager's comments come after Dinamo Zagreb's Arijan Ademi was banned for four years for failing a test after his side's Champions League win over the Gunners in September.

Dinamo have not been disqualified from the competition as regulations state two or more players must test positive before that punishment is considered.

Wenger said the rule was "surprising".

Do you not remember Paris 2006 Max?

Flobalob: Arsenal's CL future may look bleak but realistically they're not. Arsenal and Bayern can both beat Zagreb and Olympiakos.

Max Baggins-Craig: To many, Arsenal haven't really ever taken this competition seriously, they need an attitude/approach change if anything, simple.

Bayern Munich and Olympiakos meet tonight knowing a draw would take both through to the Champions League last 16 and eliminate Arsenal.

Germans Bayern are top of Group F on nine points, level with Olympiakos, after four of the six games, with Arsenal third on three points.

Elsehwere, Porto will undoubtedly fancy their chances of reaching the Champions League knockout stage tonight.

The Portuguese side are top of Group G with 10 points, three ahead of Chelsea, and need to pick up just a point against Dynamo Kiev - who have managed to win just five of their previous 35 group games. 

Finally, Lyon, bottom of Group H with one point, need to beat Gent and hope leaders Zenit beat Valencia to keep their hopes of progressing alive.

Arsenal should have the ammunition to beat Dinamo Zagreb and keep their part of tonight's Champions League bargain - but they also should have beaten Monaco at Emirates Stadium last season and Olympiakos here during this campaign.

The Monaco defeat wrecked their chances last season and the Olympiakos loss, coupled with a defeat away to tonight's opponents earlier in the group, are results that have left them in real trouble in the Champions League.

So can Arsenal be trusted to deliver? The recent evidence suggests you wouldn't back them with complete confidence.

Surely tonight though...

"It would be interesting to see Arsene Wenger give Calum Chambers a run in that defensive midfield position. We've seen how well it's worked for Eric Dier at Spurs and I think Chambers is very similar to Dier: good stature, good on the ball."

Here he is - Tal Ben Haim I has been reunited with John Terry I.

Arsenal

Arsenal respond to the injuries of Francis Coquelin and Mikel Arteta by recalling Mathieu Flamini, who recently announced that he has developed a chemical process that could reduce the dependence on fossil fuels. Honest.

Jeff Reine-Adelaide, a 17-year-old French winger described as "something special" by Arsene Wenger, is on the bench and could make his first senior appearance.  

Talk about short notice...

The League Two match between Accrington and Hartlepool has been postponed because of a waterlogged pitch.

Maccabi Tel Aviv are managed by Slavisa Jokanovic, who took Watford into the Premier League just six months ago.

They also have former Chelsea (and Bolton, Portsmouth, Manchester City, Sunderland, er, QPR. West Ham and Charlton) defender Tal Ben Haim.

And what's better than one Tal Ben Haim? Two of course!Yep, striker Tal Ben Haim (below) brilliantly goes by the name of Tal Ben Haim II. They both start. The sequel and the prequel.

The fight for second place in Group E remains tight after Bayer Leverkusen drew 1-1 with Bate Borisov.

The German side are level on five points with second-placed Roma, while Bate have four points. Leaders Barcelona have qualified for the knockout stage as a result of Leverkusen's failure to win.

Roma face Barca, who hand Lionel Messi his first start in two months after he fully recovered from a knee injury.

Zenit St Petersburg, who have already qualified for the knockout stage, made it five wins out of five in Group H with a 2-0 win over second-placed Valencia.

The Spanish side finished with 10 men after Ruben Vezo was sent off.

Arsenal have reached the last 16 of the Champions League for 15 successive seasons - but are in serious danger of ending that run this year.

However, they have also not won the Premier League in 11 years. Would going out early in Europe help life back home?

Could this perversely be Arsene Wenger's best chance of winning the title in a decade?

Let us know where Wenger should be concentrating his efforts.

"For too long the 'top four' ambition has brought Arsenal down. It's time they set their stall out to win the league. 

"If Arsenal fail to win the title this season because of failing to strengthen adequately in the summer window - it's unforgivable, not signing someone to play alongside Coquelin. If they'd signed Morgan Schneiderlin or Sami Khedira, it would have made a real statement of intent. It's poor management."
