Head coach Dean Ryan has yet to finalise his side to face Philippe Saint-Andre's men but Boer told www.gloucesterrugby.co.uk. "I have always said that if you want to finish in the top three, you have to been consistent - we need to try and develop that consistency.
"Sale are a very good all-round side with plenty of talent in the backs and a good forward pack and we will have to find a solution to the problems they will present us.
"But first and foremost, we want to put on a good performance on Saturday. Against Worcester we felt there was no rugby played which meant we didn't have too much to judge ourselves on.
"But we know if we come out with a good performance this weekend against a side who finished in top three last season, we will know where we stand with Wasps, Leicester and Sale.
"I think it's vital for us we try and put on something special and try and get a good result."
