A win would see Glasgow through to the quarter-finals of the European Challenge Cup, the first time in their history that they would have qualified for the last eight of a European competition.
A win by eight points or more could guarantee the Warriors a home draw in the next round, depending on results elsewhere, and Al believes that such a high-profile game could help to raise the awareness of the club in the city community, which has anyway been getting behind them with more and more enthusiasm as the season has gone on.
"We had a good travelling support last week out in Parma, and the crowd at our home games has been getting steadily noisier all season," Al said in The Times. "Now we want a big scalp to show what we are capable of at this level. I know the Challenge Cup is not as high profile as the Heineken Cup, and it is one of our targets for the season to win back a place in the bigger competition, but this is probably good for us at the stage of development that we are at now, and Saracens are a big club."
Saracens won the reverse fixture 28-23, and despite the Warriors having big problems in the scrum - the English side were awarded two penalty tries for scrum offences.
"We have done a lot of work on the scrum since then and brought in Peter Wright as a specialist scrummaging coach, so we are confident that we have improved a lot in that area," Al said. "We know that Saracens have one of the toughest scrums around, and we are fully aware that they will look to pressure us in that area again, but we believe we can deal with it now."
