Dyer's sparkling form left many thinking the 25-year-old could be in line for an England cap. Some pundits believe his chances of a call-up would increase if he moved.
But Dyer told The Sun: "I've seen players that have gone and not done so well.
"I've seen the run up to when players are leaving. You get to experience the whole thing with them. I'd look at what happened to others if I was in that position.
"Anyway, I'm enjoying my football so much I've not thought about the future. I've got 18 months left so I don't think it's high on the agenda at the moment."
