Sparce and yellow sounds like poor drainage. This is not the time of

brushing the worm casts (if that's what the clods are) to disperse
them.
I think you need to do the old fork and wiggle regime all over the lawn
in March/April and brush in some sharp sand to improve drainage. Then
sprinkle on some lawn feed and leave for about a month. Then re-sow
any thin patches.

2nd vote for forking holes in - I shall do that as soon as it dries out
a bit, thanks!
