Arsenal are in the UEFA Champions League for 2011-12, signifying their 14th consecutive campaign in Europe's most prestigious competition.
After much debate that the Gunners would fail to qualify due to the departures of captain Cesc Fabregas and key playmaker Samir Nasri, Arsene Wenger's men still prevailed.
With Arsenal possessing a slim, one-nil advantage from the first leg against Udinese, Gunners fans were nervous as their side travelled to northeast Italy to the Stadio Friuli.
Arsenal boasted a weakened team, missing PFA young player of the year Jack Wilshere and French defender Laurent Koscielny whilst England international Kieran Gibbs was also missing.
However the Gunners looked lively in the opening exchanges, with Gervinho and Theo Walcott both looking sharp but failing to capitalize.
Udinese were also threatening, particularly through heroic captain Antonio Di Natale.
It was the 33-year-old who provided the difference in the first half, with the Italian placing a neat header past Wojciech Szczesny to give Udinese a one-nil advantage and an equalizer in aggregate terms six minutes from the main break.
It ensured that Wenger's men went into the dressing rooms vulnerable and nervous. Wenger needed no one to remind him of the immense financial and reputational security that would diminish if defeat emerged tonight.
However, the young Gunners dominated the second half.
The injection of Tomas Rosicky alongside overwhelming desire resulted in Arsenal equalizing in the match and taking an advantage on aggregate.
Gervinho had shown neat skill in the 55th minute to attack the by line before playing a perfect pass for Robin van Persie to score.
Fifteen minutes later Theo Walcott showed great pace and an impressive finish, not before Wojciech Szczesny made a sublime penalty save from Di Natale, to ensure the game was Arsenal's and signify their presence will be felt in the UEFA Champions League in 2011-12.
