Di Matteo is desperate to bring in another striker before the transfer window closes at the end of this month.
The Sun reports that Di Matteo is keen to bring in Cavani before the transfer window closes.
Di Matteo could make a move for Porto striker Hulk, if the deal for Cavani stalls.
Di Matteo said: “I don’t know if there will be new arrivals. We’re probably a bit light in attacking positions.”
