I love that some of us are having to explain to some of the others why a footballer would want to play at the highest level possible.
We finished 9th in the Premier League - that's pretty 'high level', and the highest level is to be selected to play for your country - again, something achievable at Brighton, as evidenced by several players doing precisely that.
Not impressed by the condescending tone of your comment, but hey ho...whatever floats your boat.
