an easy statement to make but we don't control the riders - they're not contracted like footballers, they're self employed and will go where the money is, IE Poland.
And yes, Brexit is another reason - we won't be flying in foreigners at the drop of a hat, we won't be able to. So teams will be weakened, like it or not and the sport needs to reset the 3 divisions to accomodate this ensuring teams are well matched.
