If I was him, I'd delete the twitter app off my phone for a while, some of the mentions he's getting are pretty disgusting: https://twitter.com/search?f=realtim...AJackGrealish1
Just in relation to Kenny Cunningham and Brian O'Driscoll joining the debate - neither of them had to choose what country to play for, so I really don't think either of them should comment on it. I'd be more interested in hearing the opinions of players with dual nationalities - Kilbane, Keown, Clark, etc
