Question

What is in that "pack" that Nadal "sucks on" before he starts playing?

Answer 1

water OR excellence...

Answer 2

Most likely water or a fruit juice, something like that. Obviously there aren't any performance enhancing drugs in it or anything or it wouldn't be allowed.

Sometimes you'll see players eat things like granola bars or bananas before a match or during long time outs. It's not against the rules or else it wouldn't be so common.

Answer 3

That "pack" is his rhythm in order to beat his opponents & win the games.

Just wait & see how the Fed's era will soon vanish in favor of the Rafa.

good times bro.
