Sigh......
We can try all we like, but will only get a 'yes' if and when the regulations say so. We can try to make a bit for Messi.
There are a lot of things we can try but the outcome's not in our control.
I don't think the decision is our's to make - we are governed by the regulations, and so far the regulations have prevented us bringing ether of these players to Brighton. When and if that will change I don't know; I expect we'll have plenty of lawyers working on it.
