Worked out well for Pedro...
I can see the positives of it in a certain respect but given Celtic will need a complete squad overhaul in the summer, I think the potential negatives would outweigh the positives. If he comes in loses both OF and drops points in other games, he'd be a few dropped points next season from being under pressure.
It Doesn't seem worth the potential risk, when realistically you only have Turnbull, McGregor and Forrest being first team quality players left next season.
If it was us. I'd want him to sign up and instead of taking over, come in and observe the squad and training to see the quality of the players and what is needed for next season.
