Roma coach Luciano Spalletti is delighted with the form of Edin Dzeko.
The striker, however says Spalletti, can be replaced.
Spalletti said: “It can be done and I did so last season with some very good results. Now Mohamed Salah has returned we have more options to vary things up front and that will again come up during the 'reasonable squad rotation.'
“Dzeko is the only player we have with those characteristics of being a strong centre-forward figure who can hold up the ball and make his physicality count. We do have other options, playing in a different way that can give advantages, so we're covered there.
“I could do with another player like Alessandro Florenzi, as right now we've only got Bruno Peres on the right."
