The former Tottenham striker has been linked with a move back to White Hart Lane, after failing to make an impact at Anfield.
“I’ve only been here a few months but there’s nothing I can do about speculation, that’s all part and parcel of being a footballer,” Keane told the club’s official website.
“If people want to create something that’s not there it’s up to them but there’s no question in my mind, I will be a Liverpool player for a long time.
“People can write what they want and they can say what they want. They can keep writing but I’ll be here past January.”
“I’ve only been here a few months and it takes a bit of time to settle into a new club. That’s not an excuse but I deserve to be judged a little further down the line,” added Keane.
“I’m not being big headed but you don’t score a lot of goals like I’ve done over the last 10 years and suddenly it just goes away so I’m not worried about that.”
