For every one of those years, you - the fans - have shown me total support and love," Kane said on social media on Friday."That's why it hurts to read some of the comments that have been made this week, questioning my professionalism."While I won't go into the specifics of the situation, I want to clarify that I would never, and have never, refused to train. I will be returning to the club tomorrow [Saturday], as planned."I wouldn't do anything to jeopardise the relationship I have with the fans who have given me such unwavering support during my time with the club. This has always been the case as it is today."Sources have told ESPN that Manchester City are the front-runners for his signature -- with Manchester United and Chelsea also monitoring the situation -- but Spurs do not want to part with their prized asset, who they value at around £150 million.Earlier on Friday, City boss Pep Guardiola confirmed that the club were interested in Kane, but said a deal could not be made if Spurs refuse to enter negotiations."Harry Kane is an exceptionally talented striker and of course, we're very interested but if Tottenham don't want to sell... Of course, we'll try," Guardiola said in a news conference. "If Tottenham don't want to negotiate, it is finished."If they want to negotiate, many clubs would like to sign him. We are not an exception. We are very interested in him."
