Several clubs are keeping tabs on the 24-year-old, who could be included in England’s World Cup squad.
“If a big team wanted me to come and play for them, then you have got to be realistic and look at the fact it may be a right decision for both sides,” he said.
“I’m not saying for one minute I want to leave the club. I have loved my time here and the club has done brilliantly for me.
“I love all the staff and the players. But every player is ambitious and if a chance came to play for a top four team then I am sure, like most players, you would take it with both hands.”
“The club will have its own agenda but I have ambitions to go as far as I can in my career,” he continued.
“Not for one minute am I saying I want to leave and I have loved my time here. I am settled.
“The manager is understanding that probably any of our players had a chance to maybe to better their careers, I think that’s nice he wouldn’t stand in their way.
“Like I said, the club has been outstanding for me and I firmly believe I have become a better player.
“Who knows? It’s a big window and there is a lot of business done. If I stay, I won’t for one bit be unhappy.
“It’s been spoken about that I am the club’s most valuable asset but until a team comes and puts money on the table, I am going to be a Bolton player.”
