Dwyane Wade has revealed that he is supportive of LeBron James's decision to leave the Miami Heat to return to the Cleveland Cavaliers.

Wade also revealed the moment he knew James's decision without being told as they shared a long flight from Vegas to Miami the night before it was made public.

"I probably knew then, without him telling me at that moment. You could tell where someone's heart is and what they're thinking," the three-time NBA champion told reporters.

"As his friend, I'm just supportive. You've gotta do what makes you happy — selfishly do what makes you happy. The decision to go back home was that."

Wade was also asked about trying to keep the four-time MVP in Miami, to which Wade responded that he 'doesn't recruit' players.
