Charles Oliveira has warned Islam Makhachev not to treat their UFC title fight as a "joke".
The Brazilian star was stripped of his lightweight crown after missing weight back in May, but he will look to reclaim the vacant strap when he takes on Makhachev in Abu Dhabi at UFC 280 on October 22. Oliveira called out Conor McGregor after his victory over Justin Gaethje, before which he had his title taken away, but was forced with no option but to accept the Russian's challenge.
Makhachev and Oliveira have developed a war of words since the announcement of the fight with the likes of Makhachev's mentor Khabib Nurmagomedov and manager Ali Abdelaziz becoming involved. Oliveira believes that the "arrogance" of his upcoming rival's team will not phase him after previously suffering a heart condition.
