The second leg is in Munich, with Bayern hosting Sevilla at the Allianz Arena on Wednesday.
And Dutchman Robben, who was rested for the first leg, has spoken of his love for the European competition that he won with Bayern in 2013.
Jupp Heynckes' side won 2-1 in Seville last Tuesday, but know better than to take their Spanish opposition lightly.
Hargreaves, who scored the first ever goal at the ground, expects Sevilla to put up a fierce fight, but won't ultimately topple the finely-tuned Bavarians.
So it's fair to say that it's pretty hard to win that many league titles unless you last in the game for a long time, well Bayern's Kingsley Coman has completely screwed over that theory.
- In the history of the competition, there have been 312 occasions of the home team losing the first leg of a knockout tie - only six of those sides have progressed.
Coman has lifted the German league in each of his three seasons at Bayern Munich
At the time, Bayern trailed then-leaders Dortmund by five points in Germany.
However, during that winless run, they did dominate Barcelona before conceding twice late on to draw 2-2, showing once more they are more than capable of matching the continent's biggest teams.
However, for the moment he insists his "personal aim is on reaching the semi-finals". They crashed to a 4-0 La Liga defeat at Celta Vigo on Saturday. - Bayern failed to score at home in the Champions League for the first time since April 2014, with Sevilla stopping that 21-game streak. Muriel has scored nine goals this season but has not scored in Champions League.
Crucially though, several Bayern players will need to be extremely disciplined so as to be safe from suspension, with the likes of Jerome Boateng, Joshua Kimmich, Robert Lewandowski, Franck Ribery, Sebastian Rudy and Corentin Tolisso just one booking away from incurring a one-match ban.
