See other posts about players. Nothing more to say from me. Not sure why you somewhat randomly pluck QPR to make your case but there you go. All hypothetical in any case. All opinions of one sort or another.
+ talking of their comparable level as is, not the advantages if in an English league. Nothing more to say, their players are largely not in demand as things stand.
If they were that good their players would be in high demand in many top leagues, but largely they are not. Many English cast offs make the trip up there and stay, and old uns topping up the pension pot.
