It has been reported that Liverpool manager Jurgen Klopp has been keeping tabs on Forrest for several months.
Klopp is reportedly planning on making a move for the Celtic and Scotland international winger in the summer of 2019.
According to The Scottish Sun, Celtic will demand at least £8 million in order to sell the 27-year-old at the end of the season.
Forrest is one of the best wingers in the Scottish Premiership and is a key figure in the current Celtic team.
The winger has shown what he is capable of, and it does not come as a surprise that Liverpool have reportedly been tracking him.
While the Scotland international will be a good addition to the team at Anfield, it is hard to see the 27-year-old play week in and week out for the Reds.
However, the chance to play for one of the biggest clubs in the world in Liverpool and to challenge for the Premier League could be too tempting to resist for the winger.
