A sauce will contain lumps, if it wasn't mixed properly when making it.
The lumps would just be wasted thickener, and lumps are not to happen in the first place. What you do is in a separate bowl, pour some of the sauce in that bowl and mix with all ingredients you use in a roux. When that mixture is completely mixed, you then add it to the main sauce mixture and there will be no lumps if you stir it enough.
