Is "what is there for tourists" the only criteria on which you're judging places? Seems a bit narrow to say the least. Glossop, Keswick and Llangollen are tiny places so it is rediculous to compare them to Southampton or any other city.
The commentators on Solent saw a replay of the ball going out well before the kick was taken. The fourth official no doubt gave Dean a quick word before the kick was taken. This isn't strictly allowed and is why Dean didn't simply over-rule to give a goal kick. If it was allowed you'd get players and managers demanding a review by the 4th official of nearly every decision.
The fact that MP brought him on to do a job on the left side shows that he really rates and trusts him. As the poster above points out, he is still just 18.
Walcott was not far off Bale last season in terms of goals + assists. Far superior to Dyer and much much better than people like you give him credit for.
