You'd take Chalmers and McHugh over McDonald and Ainsworth. I know you don't attend many games, but jeez. From what I remember, McHugh hardly did anything in the Premiership for Motherwell, hence why he was released.
Whilst McHugh hasn't done anything notable as such at Motherwell, we do have a knack of bringing the best out of players to rejuvenate their careers. Like I say, McHugh will be 24 next month which I would still consider fairly young for a footballer, so he could be a option for a 'back up' to Ofere if he signs for next season.
Like you I would much prefer McDonald however I'm just covering all basis as to what may be more affordable for the club.
