The midfielder returned against Aston Villa on Saturday evening after a three-game absence caused by an ankle injury.
Gravenberch completed the whole match and delivered an influential display that included the Reds’ second goal in a 2-0 Premier League win over Villa.
Speaking to TNT Sports post-match, head coach Slot was asked if he will need to manage Gravenberch’s minutes for the European showdown with Real.
“It depends on how his ankle feels now,” he said. “It’s of course a difference if you’ve been out with a muscle injury or with an ankle injury.
“I think he’s able to go again, but we have to see how he comes out of this game. But I think this game also gives a bit of energy on itself to play Real Madrid.
“But it’s true that we also have to be smart about the minutes because we have 19, 20 players available normally. With three or four out, that means a lot of minutes need to go to the same players, and when they go to the national team they have to play as well.
“I think Ryan is able to play [on] Tuesday again but we have to wait and see.”
