The versatile defender has been linked with a move to Crystal Palace and Leicester City, as well as Championship side Middlesbrough, since impressing during his time with Rovers.
He signed a season-long loan deal with Rovers in the summer, with his contract at parent club Wolverhampton Wanderers set to expire at the end of the season. It is understood however that Wolves have the option of taking up a further year on his deal.
Though his own future is likely to come under greater scrutiny in the next few months, the 20-year-old says he is only focusing on performing for Rovers,
“I don’t take any notice,” he said.
“Personally, that’s nothing for me to get involved with.
“I’m just here to play football at the end of the day so I can’t be worrying about outside noise.
“I’ve just got to focus on my performances on the pitch.
“I’ve heard about it, people have told me, and it’s nice to hear.
“But in the present I’m here to play games, to play football and hopefully I just keep performing well.
“Whatever happens in January or in the summer, that's what happens.
“But I’m here for the season so I’m just looking forward to that and hopefully just doing well here.”
John made his first league appearance for Rovers in 11 weeks after recovering from an ankle injury, scoring in Saturday’s 1-1 draw with MK Dons.
