Juventus coach Massimiliano Allegri says early kick-offs in the Italian Serie A can sometimes be tricky to handle.
The Bianconeri host Sampdoria on Sunday morning in one of their rare early kick-offs of the season and the Italian believes this could affect the outcome of the match.
"Compared to last season Sampdoria are enjoying an important campaign," Allegri said.
"They have good players in the squad, excellent players, and a coach who is showing his worth. Scoring against them is not easy and they are really good from set-pieces.
"They have nothing to lose and all this means that tomorrow will be a difficult game for us, also because these early kick-offs could have a strange outcome."
Asked to give an update on injured players, Allegri added: "[Martin] Caceres and [Luca] Marrone are not available.
"[Angelo] Ogbonna will replace [suspended Giorgio] Chiellini. Ogbonna did really well in the first part of the season and he's fit. He also did well in the last 15 minutes when he came on in the derby [against Torino] so he will start alongside Bonucci tomorrow.
"As for [Alvaro] Morata, I'm yet to take a decision because I still have a number of decisions to take on the midfield and the offensive department.
"Let's not forget that Morata is a 22-year-old with amazing quality, he arrived from a league which is different than ours so he still has a lot of growing to do.
"It's normal to face competition up front, we also have [Fernando] Llorente, [Carlos] Tevez, [Sebastian] Giovinco and [Kingsley] Coman."
