Great for us that he is focusing all energy at club. After City game, he sounded like he was hoping to be selected, so to my way of thinking there are 2 main possibilities.
1. Pick me Gareth....I've been selected? shove your pizza hut up your arse.
2. Doesn't want to be 'part of squad' for qualifying, and otherwise there will be a media circus around each squad. Announce retirement and come out of retirement if needed, or at World Cup. No guarantee of selection, but likely to merit a place in squad.
