To be fair to Mullen I thought he was decent when I saw him play ( aside from Sunday obviously)

Would be nice if people could lay off Mullen. Yes he got caught in possession against Celtic, he'll learn from it. Way to early to be trashing Mullen as he has hardly played for the club.

I'd like to think the club have been exploring any possibilities since Sunday. Not ideal at this critical time of the season.  Surely anybody has to be better than Mullen?
