Julio Baptista is desperate to establish himself in Roma coach Claudio Ranieri's plans.
"I played badly at Siena," he confessed. "But that was down to the tiredness that had accumulated during international duty and the flight from Brazil.
"If [Coach Claudio] Ranieri asks me to step on to the field, I will be ready, as I am finally in good shape.
"Tomorrow it will be a very Brazilian Roma. We care about the Europa League and want to go all the way."
