I still feel that Morrison is one of the few creative quality footballers that we have in our side.
Personally when you see the like of Jake Livermore's name banded about how can anyone in their right mind think about letting Morrison leave?
I believe myself to be sane so here goes trying to make a case for letting him go (always assuming he wants to stay at the club in the first place)
Q1. Does the coach want to play with a 3 man central midfield?
No go to question 2,
Yes go to question 4.
Q2 Does the coach want to play him in an alternative position e.g. Wide Right?
Yes go to question 3
No let him go
Q3. Is the player happy with that role?
Yes Go to question 4.
No let him go
Q4. Is he likely to be the first choice player for the likely duration of the contract e.g. 3 years?
No Go to question 5
Yes Offer him the best terms possible.
Q5. Is he the first choice player in his position next season?
No Let him go
Yes Offer terms that reflect this but become conditional in the latter years of the contract e.g. options in the club's favour appearance clauses etc..
I think that is a rational framework without threatening anyone with the bogeyman that is Jake Livermore although he is a very different type of player to Morrison.
