God I really hope it's one of the younger players, preferably Zverev, Thiem or Dimitrov. I will say this, if any of the Next Gen guys end up playing Fedal throughout the fortnight they really need to go into the match with a "you're the past, I'm the future" type mindset, similar to young Alexander in the Montreal final last week where they actually impose their games on their opponent, have belief in their abilities and stop being so sh1t scared just because it's a legend of the game on the other side of the net. Let's be brutally honest, Federer having a 3 slam season at this stage of his career would be embarrassing for the sport and don't even get me started on the possibility of Nadal winning a 3rd title.
If any pro players under the age of 30 competing at this year's US Open are reading this, here's a piece of advice, direct from me to you:
GO HARD OR GO HOME!!!!
