Yes they were. So it's way too early for us to make a judgement on Charlie at this stage of his career.
It doesn't seem like a debut is likely this year but if he does the hard work he can still get a lot out of the season (we aren't even at half way yet) and especially the off-season.
He could do a lot worse than model himself on Arty's attitude, even if they aren't the same type of player. Arty was indeed nowhere near getting a game this time last year.
