Have to agree Kevin 46 or 42 as a minimum
If the thought is of expansion then we really must look at splitting the division with (say) a 48-49 average for the top half and the 40 quoted for the lower half allowing those CL teams that wanted to make the step up lives a little easier
As with all things we will await the mess that is the EL to sort itself out and then the PL will have to pick up the pieces
