Carlos Alcaraz says it will be a "dream come true" to face Rafael Nadal on his 18th birthday at the Madrid Open.
The Spanish youngster beat Adrian Mannarino 6-4 6-0 on Monday to secure his maiden ATP Masters 1000 match win.
The result made 120th-ranked Alcaraz the youngest match winner in Madrid - eclipsing 18-year-old Nadal's record in 2004 - and ensured he will next face childhood idol and fellow countryman Nadal on Wednesday.

"It's the best present for my birthday," Alcaraz told Tennis Channel. "To play against Rafa here in Madrid in front of the Spanish crowd, I will never forget this moment and I will learn from him."
"I don't know how to describe this feeling now. It's a dream come true."
"They always say the 18th birthday is special, but it will be even more special to turn 18 playing against one of the best tennis players of all time, and the best for me."
