Chelsea have won just two of their eight Premier League games so far this season, while Falcao has scored just once for the Blues since joining the club from Monaco in the summer.
“Mourinho’s a great coach. He is ambitious and a winner,” said Falcao. “He has great skills to train us but results have not helped us.
“We have the quality and skills to change this and reverse the situation. I’m still fully motivated.
“My moment will come. I’m fine, I’m improving and increasingly I feel better.”
