This week our statistician Josh James looks at a Champions League landmark.
Wednesday's defeat to Schalke was Arsenal's 150th game in the Champions League (including qualifiers). The Gunners are the sixth team to reach the landmark.
Arsenal have won exactly half (75) of those games, drawing 36 (24 per cent) and losing the other 39 (26 per cent). One hundred and forty of the games have been in the UEFA Champions League proper, the other 10 were in qualifiers or play-off matches. Arsenal won all 10 of those games.
The team have scored 237 goals from the 150 matches, at an average of 1.58 per game, and conceded 151 (1.01 per game). The total goal difference so far is +86.
This is the Gunners’ 15th consecutive season in the Champions League (ever-present since 1998/99), so until this season the Club played an average of 10.5 Champions League game per campaign, winning 5.2 of them.
The vast majority of the matches (105) have come in the group stages, with 10 in the qualifiers, 18 in the first knockout stage, 12 in the quarter-finals, four in the semi-finals and one game in the final itself.
Arsenal's win rate of 50 per cent puts them in sixth place among Europe's elite. The defensive record is worth noting too. At a fraction over a goal a game conceded, the Gunners have a better record than Real Madrid, Bayern Munich, Porto and Juventus in this regard.
The most common scoreline for Arsenal in the competition has been 1-1, with 18 such instances recorded so far.
Indeed Arsenal's first ever match in the competition ended 1-1. The debut match was away to Lens on September 16, 1998. Marc Overmars scored the Club’s first ever goal in the competition under its current guise, only for Tony Vairelles to fire a last-minute equaliser.
Arsenal have kept clean sheets in 55 of the matches (37 per cent) and failed to score in 35 (23 per cent).
There have been 25 different scorelines, ranging from a 7-0 win (over Slavia Prague in October 2007) to 4-1 defeats (recorded twice).
Wednesday's 2-0 reverse was the fifth time Arsenal had gone down by that scoreline, and the defeat also ended a remarkable sequence. It was the Club's first Champions League group stage loss at Emirates Stadium (from 20 matches) and the first time Arsenal had lost at home to non-English opposition since September 17, 2003 (3,325 days).
Inter Milan were the last continental visitors to see off Arsenal in London, recording a 3-0 win at Highbury in the opening game of the group stage in 2003/04. Arsenal took just one point from their first three games that season, yet still qualified for the knockout stages.
Since that Inter defeat, Arsenal had played 45 consecutive home games against non-English teams, winning 36 and drawing the other nine, before Wednesday night's defeat. Incidentally, it was also the first time the Gunners had ever lost a Wednesday fixture at Emirates Stadium (from 31 games).
Arsenal have faced teams from 20 different countries in the Champions League so far. Spain have provided the most opponents (25), accounting for 16.7 per cent of all Champions League games the Gunners have played.
Next come Italy (20 matches) and Arsenal have recorded more wins against Italian sides (10) than any other country.
Arsenal have won at least one fixture against all the countries they have faced, apart from England. Arsène Wenger's men have met Chelsea, Liverpool and Manchester United in the knockout stages (teams from the same nation cannot meet before this time), winning none of the six games so far.
The 150 fixtures to date have been played against 52 different teams, the most common fixture being against Barcelona - having met the Spanish giants seven times. This includes the 2006 final in Paris. Arsenal have won just one meeting with Barcelona, drawing two and losing the other four.
The team Arsenal have recorded most Champions League victories over is Sparta Prague. The Gunners have beaten the team from the Czech capital in each of their six meetings.
Thierry Henry has played in just over half (77) of all of Arsenal's Champions League matches, and is not surprisingly the leading scorer too (35).
From the current squad Theo Walcott leads the way in terms of both appearances (46) and goals (10).
None of the five most experienced Champions League players in the squad were involved on Wednesday night. In fact, of Arsenal's starting XI, Aaron Ramsey had played more games (it was his 22nd outing) and scored more goals (three) in the competition than any other player.
