Main quotes from Valverde and Di Francesco prior to Roma vs Barca
• Eusebio Di Francesco asks critics not to judge him heavily: "Remember, Barcelona have not been built overnight. This team has been built over years, not just five or six months or a few days. This is Barcelona's main strength. I'm nobody here. I'm just part of this club. I convey my thoughts with conviction. I aim to put great passion into my work, with the good and the bad, and I have to try to make as few mistakes as possible."
• Meanwhile, Ernesto Valverde is taking nothing for granted: "We mustn't think we've already won. We got a great result in the first leg but that's it. We've got to play like it is 0-0 because anything can happen. We've got to aim to win the game and not think of anything else. I always think we can lose, in the same way I always think we can win. We have plenty of things in our favour. They've got good players, though, and we have to be ready for that."
