The Walsall midfielder has been the toast of the town at the Banks's Stadium of late, capping some fine performances with two goals in his last two games.
And ahead of Wales' two UEFA Under-21 Championship qualifying matches against Luxembourg, Flynn has backed Bradley to make the step up to the senior squad without any difficulty.
"He's a manager's dream player," said Flynn in the Express and Star. "As a midfield player you need discipline to play in a certain role, fantastic energy levels and a knack of popping up in the right place to score.
"He's got those three attributes and is going to go a long way. I've got big hopes he is going to push in to the senior side. In the international game you've got to have ability and attitude and he's got them."
