Speaking to Sky Sports, Driver said: "I'm happy here. "I'm on a good contract and the way things are going I wouldn't want to spoil it.
"I wouldn't want to miss out on what this team could go on and do.
"Ultimately, you want to play at the highest level and to do that you have to go down to England eventually. "I don't know when that will be but when the time comes I think I'll know."
