Spurs boss Harry Redknapp has confirmed his interest in Forrest.
Reports have suggested Spurs could make a move for Forrest before the Januaryt ransfer window closes.
“It is obviously good to hear, but it doesn’t bother me,” said Forrest of being linked with Spurs.
“The main thing is I want to keep playing well with Celtic.
“I am not thinking about it. We’ve still got the second half of the season to go with Celtic.
“It is still early doors right now and all we need to do is hopefully keep our good run going and keep winning games.
“As long as I’m doing well and the team’s doing well, I am happy.”
