Gareth Bale is back from injury, but Zinedine Zidane is not looking to risk him against Napoli on Wednesday.
The Wales star has been out of action since November, but he returned to training with the team this week.
Although Zidane acknowledged Bale has looked in good shape in recent days, he remains uneasy about the prospect of rushing him back after close to three months without a game.
“It’s the first week that he’s trained with the group,” he told a news conference. “He’s good, he’s good physically and mentally, which is the most important thing.
“We’ll see if he can be in the squad or if he’ll be there at the weekend,” he added, referring to the impending visit of Espanyol in La Liga.
“At the same time, after two or three months out, we have to be very careful with Gareth.”
