The Germany star has struggled for fitness all season but the Bayern Munich sporting director says his injury problems will be behind him by June.
The Germany international has struggled with injuries all season but recently returned to action following ankle surgery back in November.
However, the 46-year-old insists that there will be no question as to whether the midfielder will be fit and firing for the Brazil tournament.
"For God's sake, he will be fine for then!" he told Bild. "He's a leader, regardless of his fitness. He is the leader along with Philipp Lahm and Manuel Neuer. I count Dante among them too.
"Bastian directs the group. He needs to be properly fit, use each training session and every minute to come back. This may take a week, it may take four."
