Glasgow face a trip to Scarlets, a home match against Ospreys and finish up with trip to Connacht on Friday as they seek to stay top of the PRO12 table and secure a home play-off.
Al told the Evening Times: "The target for us is a home semi-final in the play-offs and to do that we need to wheel out the old cliché and say it has to be one game at a time over the last three fixtures.
"What we have to make sure is that this last stretch is all about us. Make sure we produce a performance in each one of these last three games that will set the bar and put pressure on everyone else.
"We showed tremendous character to come back from a gut-wrenching defeat in Leinster to take out Munster in such emphatic fashion, but now we can't afford to look further ahead than the Scarlets game on Friday week.
"They beat Dragons at the weekend and will want to win this home game. So the last thing we can afford to do is let our minds stray.
"At this stage in the season it is great to have a week off and particularly so after such a huge physical effort against Munster.
"On top of that we got through the game without any injuries. That is another positive for us."
