I'm expecting 14th too but it's all academic. Does anyone really expect SL to expand? Will SL clubs really want to see their share of TV money go 14 ways instead of 12? I remember when they decided to keep our SL money from Omar Khan back in 2013, effectively ruining the club from the start. There's no way those same clubs will vote to expand the competition if they lose money as a result.
The only way in is if a SL club utterly implodes and then the 13th club will get to make up the numbers or if we get a rich sugar daddy who's prepared not only to fund everything to get an A grade - even then they'd probably need to assure SL that they wouldn't ask for their share of TV money. Then, maybe.
We'll probably need to wait a few years before everyone realises that deciding where clubs sit by checking a spreadsheet every October isn't working and we go back to how things were. We had this under licensing and I didn't spot any improvements then.
