Under what possible right do you think Spurs would have the ability to sue Nottingham Forest over a contract between Morgan Gibbs White and Nottingham Forest ?
I will answer that, none.
They could possibly support MGW in him filing a legal complaint, but Spurs do not have any rights here, as they are not party to the contract.
Note this is different to why Forest could potentially sue Spurs, if it is deemed Spurs coerced MGW to break his contract and then used that known breach for its own commercial benefit.
EDIT Shouldn't have asked, as you will now post another 50 things on this thread today, changing your mind 20 times after saying you will duck out of thread 3 or 4 times
