Real will take on the Catalans at the Nou Camp on Saturday with a six-point advantage over their fierce rivals in the La Liga standings.
Zinedine Zidane's side are top of the tree with Barca second, and victory for the capital club would put them in pole position to win the Spanish top-flight title even at such an early stage of the campaign.
A match between the two giants is always a tense affair and, without nailing his colours to the mast in as many words, Tebas hopes that Spanish football, and Real, are the winners.
"I want the Clasico to be a big party for all of La Liga to benefit from," he said. "But I won't say who I want to win because you already know who."
