Milwaukee Bucks coach Jason Kidd believes that if his Greek superstar Giannis Antetokounmpo works hard enough, he can be the best player on earth.

The 21-year-old was recently voted as the best international player in the NBA by the league’s general managers and has recently signed a four-year, $100 million contract extension the richest contract in Bucks’ history.

And Kidd predicts even more for Antetokounmpo.

“That’s a great honour because the names just mentioned are all very talented and all could be that player,” Kidd said to the Milwaukee Journal Sentinel.

“That’s a great compliment to him and what he’s done, working on his game and getting better. Now it’s not just to stop there as the best international player, but hopefully one day to be one of the best players in the world.

“Nothing surprises me in this league. It just shows how hard he’s working and the way he’s perceived in this league, how GMs think about him.”

Kidd’s comments were echoed by the lanky Greek, who knows what he has to do.

“Do I get a trophy or something?,” he said.

“I feel like I’ve got to work more. Being above Dirk and Marc Gasol and Pau Gasol, they’re really good players. So I’ve got to show on the court – the GMs that voted me – that I deserve it. I’m really happy.”
