Not true, if the club refuse to sell then he won't go in the simplest terms. It is when Rom can force the move through himself that he would leave, and even then it is based on someone paying his valuation.
Personally though i believe his head turned in the stoke game, 2 goals and an assist and then we lose 4-3? Why would he even want to stay playing for us after that? Especially as the game keeps repeating anyway in our season.
One hope of keeping him is replacing the manager and showing a little ambition in who we bring in, just make the lad a deal, sell him in 12 months if we aren't challenging up there.
At the end of the day Rom only has a finite amount of time in his career so if he knows he can deliver a world class return on a regular basis then we will want to do that for a team who can turn his 20 plus goals into success, not one that turns them into 4-3 defeats at home!
What will have changed his mind is scoring and losing games, with the current manager not changing how we play. If we sacked Martinez tomorrow for arguments sake, stuck someone in temp charge but shown some ambition in his replacement then that might convince him to give it one more year.
Remember Roberto doesn't convince players to stay, hence Stones transfer request....
