Juventus secured a place in their first European final since 2003 following a 1-1 draw with Real Madrid on Wednesday which sealed a 3-2 aggregate victory.
Messi helped inspire Barcelona to a 5-3 aggregate triumph over Bayern Munich in the other semi-final but, while Tevez admits the 27-year-old can do "crazy things", he is confident in his own side's chances.
"Messi is the best player in the world, even in the semi-finals he did crazy things. He is a player from another planet. I never had problems with him," Tevez told Sky.
"We deserve this final. Now we go to Berlin for a big challenge against Barcelona. Ours is really a team, no one would have bet on us but we've done something great."
Tevez was also keen to praise the tactical planning of head coach Massimiliano Allegri as Juve continue to chase an historic treble.
"Allegri prepared these two games perfectly. He always gives all the credit to us but much of it belongs to him," he said.
The former Manchester City striker has been linked with a return to Argentina in the summer but he insists his future remains far from certain.
"I've not decided anything," he said simply.
