Tyjon is being badly advised if he thinks going to Arsenal is best for his career. An immediate increase in earnings, yes, but at the expense of developing his game long term.
He'll never play for Arsenal, who will ship him out on loan after loan, just as Spurs do with Phillips (who can't get a game for Stoke). The guy who went to Newcastle (who's name I can't remember) would probably be a regular by now in our team.
Play in the championship and learn to play men's football, like Wharton did, and you'll get a big money prem league move if you're good enough.
Rovers is a great club for young players as you will get a very good chance to play regularly with our lack of investment in established players and thin squad.
