After traversing the difficult challenge of AC Milan, all eyes are on CSKA Moscow for Arsenal as they enter the quarter-finals of the Europa League.
Cut 12 points adrift from the Premier League top four, it's quietly accepted that Arsenals chances of Champions League qualification depend upon success in Europe's secondary club competition.
The prospects of Marseille and Atletico Madrid will certainly worry the Gunners yet the draw of CSKA Moscow, for all intents purposes, seems a positive one.
The Russian side were defeated 4-1 and 2-1 by Manchester United earlier in the season and have notoriously struggled against English sides in recent years.
However, their major success against Premier League opposition came against none other than Arsenal in almost forgotten 1-0 victory back in 2006.
In fact, Arsenal are yet to defeat the Russians in the two games they've contested with a 1-0 defeat in Moscow and a drab 0-0 draw at the Emirates Stadium.
So where did it all go wrong for that Arsenal side in October 2006? Well, multiple reasons no doubt - but below is the Arsenal squad that suffered defeat on that very day and it makes for interesting reading.
Arsene Wenger deployed some of his most trusted servants, yet it was in vein after Daniel Carvalho's won the game for home side. Check out Arsenal's team below and how they have fared since:
Something of a legend in north London, Lehmann stood between the sticks for the Invincibles and stayed until 2008. He spent two seasons with Stuttgart, returned for one last appearance with Arsenal and retired in 2011.
One of 68 appearances Hoyte made across six years at Arsenal until his eventual departure for Middlesbrough. Has spent time with Millwall, Dagenham & Redbridge and FC Cincinnati since.
Fresh from his Chelsea exit, Gallas would go onto spend four years at the Emirates Stadium only to switch allegiances to Tottenham. Retired after a solitary season with Perth Glory.
Another member of the Invincibles near the end of his time with Arsenal. Toure had enjoyed the best spell of his career, yet still secured moves to Manchester City, Liverpool and Celtic before his 2017 retirement.
The Swiss international made only two appearances this particular season across a decade-long spell in an Arsenal shirt. He eventually left in 2013 and now resides at Samuel Eto'o's Antalayaspor via Hannover and Hamburg.
A cult hero at Arsenal and with good reason, 'Little Mozart' amassed 247 appearances across 11 years at the club. He hung up his boots last year after a two season swan song with Sparta Prague.
Just the 54 appearances for Fabregas this season as he made his major breakthrough in Arsenal team, remaining until 2011. He spent three campaigns at Barcelona before moving back to the Premier League with Chelsea.
The World Cup winner had passed his prime by the time he stepped onto the pitch in Russia, leaving for Panathinaikos in 2008. Silva retired after further flings with Gremio and Atletico Miniero.
A man who was always regretted turning his back on Arsenal and a man who thrived in the red jersey. His 2008 move to Barcelona never really worked out and he has played for seven clubs since.
Robin van Persie
No longer a popular figure at Arsenal but a prolific goal scorer for the club during his time there. His initially successful Manchester United move eventually fizzled out and encouraged time with Fenerbahce and Feyenoord.
The final full season at Arsenal for the great man himself. Henry pulled on the Arsenal shirt during a brief loan spell in 2012 having flourished at Barcelona and pioneered with the New York Red Bulls.
