The Juventus striker netted a late equaliser in Wednesday's 2-2 draw at Stamford Bridge, then bagged a brace for last night's 2-0 victory.
"This has been one of the greatest weeks of my life. Today I wanted to prove that I was ready and I think I did that," he told Sky Sport Italia.
"It was obviously very pleasing to receive a standing ovation from fans when substituted and I thank them. It means I did my duty.
"Will I start against Fiorentina on Tuesday? We'll see. I will ensure that I am ready when called upon and I feel in good shape, then it is up to the Coach to decide."
