It's the first Aviva Premiership fixture at Kingsholm since Boxing Day when Gloucester demolished Wasps in front of a sell out crowd.
The England Saxons have finished their spring fixture calendar which sees Freddie Burns, Rupert Harden, Jonny May and Nick Wood all available again.
Also released from England and Scotland respectively this weekend are Charlie Sharples and Rory Lawson.
As a result, it's a much changed Gloucester side which will line up against the Saints on Saturday and Redpath confessed that it's good to have selection options this weekend.
"Numbers have been pretty bare this past couple of weeks and it's good to have the boys back.
"I think it's going to be a very tough game - Northampton lost to Bath recently and then went out and beat Wasps by 50.
"You've got to respect what they are, they are a very good side. They're very big and physical but have added a bit of flair with the likes of Lamb and Pisi.
"It's going to be tough. They are missing quite a few players but we have to concentrate on what we are and make sure we perform. We have to look forward to it and not shirk away from it."
