Firstly, with regards to the 4 additional countries.....this will improve the tournament and I cannot see any negatives around this for any of the UK / Irish teams. Secondly, a bit of respect for these players please, no more talk about Hungarian grandfathers etc.
With regards to the makeup of the UK / Irish teams, looking at the most recent published rankings, I can see that the highest ranked English player that has won an APAT National event is ranked in 16th position and way off the top 4 English players. I expect the Captains to be mature enough to look at all of the factors in determining their final selections. I would include Rankings very much in that. But it does lessen the hand of a Captain if they cannot choose players strategically. That said, it would not surprise me at all if each of the UK / Irish teams are picked solely on Rankings.
