Plus... If he goes out on loan next season he'll nearly be 22 when he comes back. Most top clubs young players will already have 50 premier league games under their belt by that age.
As a highly promising full international player that has experience of playing in European club competition (Not to mention the players and managers that have seen him play and train who say he's already excellent at attacking and 'very solid' at defending), I firmly believe he should be with us next season, learning from the coach, manager and better quality of players, both with and against. Coleman is holding us back now, as great a servant as he's been. Teams know we only have attacking strength on one side and as soon as he's pressed he hasn't got the ability on the ball to cope.
