New Bayern Munich coach Niko Kovac is convinced by the quality of Ante Rebic.
The Croatia international winger is being tracked by Bayern and Tottenham while he's at the World Cup.
Kovac worked with Rebic when coach of Eintracht Frankfurt and admits he remains a big fan.
"He's an excellent player, I'm glad he plays so well in the World Cup. He would be an asset for all teams," said Kovac.
The 24 year-old scored nine goals in 28 appearances last term, including a brace in Frankfurt's shock German Cup final victory over Bayern Munich.
