As his team prepared to host Ajax Amsterdam in Tuesday's Champions League Group D clash, the construction magnate told delegates at a general assembly on Sunday a first continental crown since 2002 was within reach.
"We've increased the talent of the squad, rejuvenating and improving it," Perez said.
"We have the best players in the world and they are reinforced by the academy.
"We're on the right path, sailing the right course; we've laid the groundwork for it to be so.
"The pursuit of victory is part of the identity of this team and we want the dream of winning our tenth European Cup title to come true soon."
Real were knocked out in the semi-finals last season by bitter rivals and eventual winners Barcelona in Mourinho's first term in charge.
They began their campaign with a less-than-convincing 1-0 win at Dinamo Zagreb and warmed up for Tuesday's game at the Bernebeu with a 6-2 La Liga win over city neighbours Rayo Vallecano but had to come from behind after conceding after only 12 seconds.
Real scored six goals without reply when they played Ajax home and away in last season's group stage.
