Former Arsenal midfielder Emmanuel Frimpong seemed to be struggling with his maths on Tuesday night . The 23-year-old asked on Twitter : ‘ If Arsenal win 2-0 they go through ? ’ No , afraid not , Emmanuel . Arsenal officially had 1,200 fans in the Stade Louis II — but an estimated 5,000 were in the 18,000 crowd with Monaco having put the tickets on general sale . Despite their renaissance , the Principality , with a population of 38,000 , unsurprisingly struggles to fill the stadium , even on big European nights . Five thousand Arsenal supporters packed in to the Stade Louis II for their tie against Monaco on Tuesday . It perhaps should come as no surprise that a tax haven inhabited by the super rich should lack passion — but it was difficult to avoid the comparison with the ferocious atmosphere of Atletico Madrid ’ s Vicente Calderon Stadium , the other venue hosting a Champions League fixture on Tuesday night . Monaco ’ s Stade Louis II stadium had all the intensity of a yacht club soiree . This was Arsene Wenger ’ s first win as a manager against Monaco . He had previously drawn four and lost three . Despite Bono , Larry Mullen and the Edge all of U2 fame , watching the game from the stands , Wenger and his side still couldn ’ t find what they were looking for in Europe . Bono ( right ) , Larry Mullen ( centre ) and the Edge were in Monaco for the Champions League showdown .
Emmanuel Frimpong , the Arsenal old boy , posted the question on Twitter . He appeared confused by the away goals rule in Champions League . Arsenal won Five thousand-0 at Monaco , but failed to progress after miserable first leg . 2 Arsenal supporters were estimated to be in Stade Louis II .
