While I agree on a main point - Rabiot not elite - and admitting I didn't watch any Leicester games in full, I still wonder how low you aim.
There's a number of ifs in both cases, and even when met, they're Fred/McT replacements at best, aren't they? And one of them will make noise, that's almost a given.
You want to add a dickhead for being a dickhead, and a could-get-back because he's exactly that? I'd rather not; point being if incoming players aren't proven top tier guys, but fillers, you might as well go with promising talents that are Reds already. I'd rather spend big on few guys, one at a time, spend the salary money more acutely, and broadcast the message that you don't wear this jersey if you're tier b. Leicester is a place for such mediocrity.
Edit:
@golden_blunder wait until I post a limerick for you!
