On April 4 2009, Arsenal made it 17 games unbeaten with a 2-0 victory over Manchester City.
That season, Arsenal would go 21 successive games unbeaten in the league.
Their last loss was against Manchester City on their turf with goals from Stephen Ireland, Robinho and a teenage Daniel Sturridge sending the Gunners packing 3-0.
However, in April, Arsenal managed to exact their revenge with a 2-0 win at the Emirates. Emmanuel Adebayor scored both goals against what turned out to be his future team.
Arsenal wouldn’t suffer a defeat in the league until 10 May when Chelsea would visit the Emirates and thrash the Gunners 4-1, despite Arsenal previously winning 2-1 at Stamford Bridge back in November 2008.
Arsenal’s impressive unbeaten streak meant that they managed to finish in fourth place in spite of their inconsistent first few months to the campaign. However, despite not losing for from November to May, they drew a lot, causing them to drop points and ultimately lose out on the title race.
Manchester United won the title, followed closely by Liverpool with Chelsea in third. Arsenal finished a massive 18 points behind the leaders.
