Manchester City's Brazilian striker Jo is adamant that he will prove his worth at Eastlands, despite having made a slow start to his time in England.
The 21-year-old has scored three times in 15 appearances since his arrival from CSKA Moscow, but the South American insists that he still believes in his own abilities.
He told The Sun: "I was playing for Brazil when I had just turned 20 and that's not easy.
"I've had success in my own country and I moved to Russia when I was young and won things there with a good goals record.
"I have a lot of experience despite my age and have no questions about my ability. I'm a calm player with lots of confidence in myself.
"I know the project at City is just beginning. There is a lot of competition for places and I have to prove myself."
Meanwhile, Jo's former colleague at CSKA, Vagner Love has hinted that he could be about to join his compatriot at Eastlands in the January transfer window.
He told the Daily Express: "It is my aim to go to England.
"I have given my best years to CSKA and it's time to move, but I'm not a replacement for Robinho - I am my own player."
