The teen is one of only a few Real players who are in good form.
But Solari says, "We don't know whether he'll be involved tomorrow, we need to wait a bit before announcing the squad list, but we'll know either way during the course of the day. Real Madrid's strength lies in the group, the squad is made up of 24 players. It's true that it's always tough for very young players to come into a team that has won the Champions League three times in a row. It's a positive sign that an 18-year-old lad has come in and is performing so well."
Solari admits Mariano Diaz could be an option.
"He's getting stronger and we'll announce the squad list later on today. All options are still open for tomorrow's game."
