Thanks mod for reopening, and thanks Tadpole for also noting the point that I was not asking for performance comparison, but rather whether anyone has successfully bought either on FM 11.
madsheep, scout reports don't always give a likely price (and they don't here for Mueller). I've also made many aggressive offers (including clauses and players too), and can of course continue the process BUT the price is getting high so I thought I'd just cut to the chase and see if anybody actually bought him on '11 (and if so, what they paid).
Thanks!
