Former Chelsea, Napoli and Juventus boss Maurizio Sarri appeared to become embroiled in a war of words with president Claudio Lotito after he criticised the clubs' recent transfer market dealings.

Sarri said: "I started off with a list of players who were my 'A' choice and had a list that went all the way to 'Z'. Some of the players who arrived were closer to the end of the list. I ended up saying yes to other players.

"Everyone knows full well that the players I targeted did not arrive, so I have to make do with what I have at my disposal."

Lolito though hit back at Sarri and said: "The reinforcements were strong. There is no gap between us and the big teams.

"In every club in the world, the signings are decided by the managers and furthermore the last transfer market has nothing to do with what is happening. We need a cohesive spirit to get out of this moment, including from the manager."

Celtic will be hoping to take full advantage of any behind-the-scenes turmoil with the Romans heading into such a vital European clash.
