Carew has been linked with a move to West Brom after falling down the pecking order at Aston Villa following the arrival of Gerard Houllier as manager.
The Norwegian striker is out of contract in the summer.
Newton said: “We are interested in Carew, there is no doubt about that.
“It’s no secret and we will see where that goes from here.
“We know that he will bring us something different with his physical presence and that is exactly what we are talking about.
“He is a big personality as well and that can help us in our situation.”
