Chukwuemeka is a brilliant player. If you think Iroegbunam is good then he is not even on the same page as this lad. Villa (my team) didn't want him to go but he wouldn't sign a new contract and wanted more game time so off he went to Chelsea. Did money make a difference, of courser, but also Chelsea were better placed then Villa at the time for him to further his career. He did break into their starting eleven too as I recall but injuries then dealt him a severe blow and because of how Chelsea are now run they just buy rather than develop.
If you could get him on loan then he'd be a great acquisition and would be your best player, never mind midfielder. he is that good, with the ability and age to be even better. So why don't we get him? A little bit of we don't need him now and would want a more experienced number 10 for CL football. Plus, there's a little bit of 'fk him' when considering any potential return to VP. Duran was forgiven for his crossed hammers, but Chuk will have to wait a little longer before we would want him back within the fold.
