would you give a load of money to someone not commited

I wouldn't

would you buy the missus a new car if she was shagging around and you had heard she would be moving on

save it for the lad willing to commit to the toon

not someone holding a gun to everyones head

that's not how you negotiate

why not have a clause in it saying
I will sign a 5 year deal
but I get 40mill this window and an increase of say 15% per season plus the league position bonus and all the extra money from the 4th round on in the cups

that's negotiating
both parties know where they are and what they need to deliver both on and off the field
