Toure signs for the Reds on a Bosman.
"Iâ€™ve played against him (Toure) numerous times and he is a fantastic player," Fowler told Liverpoolfc.com.
"Iâ€™m sure coming to a new club will spur him on that little bit more and he will want to do well. He will want to play. I think he will try hard in training and a little bit of pride will set in.
"You look at his performances over the years for Arsenal and Manchester City - he has been magnificent in the Premier League. Letâ€™s hope that he comes to Liverpool and carries on that magnificent form.
"Heâ€™s been a fantastic player. His experience will be vital for Liverpool, especially after losing Carra. Carra was unbelievable for Liverpool and, if anything, he was probably Liverpoolâ€™s best defender last year. He will be a big miss.
"I donâ€™t know if Kolo Toure will play all of the games, but Liverpool as a team and a squad certainly needed a lot more numbers. Brendan is doing that right now. Toure has been there and worn the T-shirt in the Premier League so I think his signing is absolutely magnificent."
