The 31-year-old has been linked with a move away from Villa Park after falling out of favour since Gerard Houllier took over as manager at the club.
Di Matteo confirmed: “They (Villa) know of our interest (in Carew).
“But obviously it has been a bit hectic there the last couple of days (with the Bent signing).
“We have a few other options as well that we are pushing forward with.”
