Former Inter Milan striker Adriano is battling for his future at Flamengo.

"I will no longer accept behaviour like this," slammed Flamengo coach Cuca in newspaper O'Globo.

"Whoever turns up late or misses training entirely simply won't play in my team any more. I don't care if it's Adriano or anyone else."

L'Imperatore infuriated Flamengo this week when he was caught by photographers on a beach during a skipped training session.

"Unlike Ronaldo or Romario, who are both extremely technical forwards, Adriano is a player of brute strength," added Cuca.

"He needs to be in perfect physical condition to give his best. He needs to train and work harder than anyone else."
