Leonardo claims Inter will still have a say in who wins the Scudetto and the Coppa Italia this season.
The Nerazzurri were eliminated from the Champions League in midweek, but still have a chance of winning some silverware from here until May.
Despite a 3-0 defeat to Milan in the Derby della Madonnina earlier this month, Inter remain in third place, five points off the lead, and play Roma in the first leg of the Coppa Italia semi-final next Wednesday.
"We can still say our bit in the League and in the Coppa Italia," Leonardo said.
"For me, nothing has changed. I arrived in January to get to important objectives and I am here as if it were my first day.
"We are constantly looking for a result and, like all trainers, I have to find it.
"I am thinking about the remaining six games of the season in Serie A and the Coppa Italia
"It's true that, in recent weeks, opinions have changed. But I am not doing a job to avoid criticism or to get praise. The criticism hasn't made me change my mind. It helps on many occasions.
"It's a paradox, but at times criticism gives you freedom in your decision-making.
"This is not the moment to give opinions on my future. Instead we need to concentrate in order to still do something important this season."
