Nadal has played every single day 4 days in a row and this will be 5. not to forget he had won the tournament before that which was just 3 days in between. 1 day travel. 1 day getting ready and still feeling it in the legs. thereby nadal isnt the youngest anymore. Thiem was earlier of from the previous tournament. and he had one day of. and only played 3 matches in a row before this match against nadal. Thiem will win. He wins at least one set. Which he will. Means in the best case Nadal needs to play a 3 setter. Something he doesnt have the stamina for anymore after the last matches in the past 2 weeks.
Mlad will take a set also.
