Roma coach Eusebio Di Francesco says Liverpool's 2-2 draw at West Brom confirmed his belief about them.
Roma warmed up for their Champions League first-leg clash with victory over SPAL.
On the Reds result, Di Francesco said: “They're not very solid in defence, but Liverpool are the kind of team where if they score six and concede three, they're happy. We start out by defending as a team and then work on the attacking movements.
“Liverpool are a side of great quality. The first leg is away from home and that can be an advantage, but also makes it very difficult to prepare tactically. I know the starting XI, it's all planned, but I won't tell you… I can say that Edin Dzeko will play."
