Sir Alex hinted strongly at his pre-match press conference on Friday that Javier Hernandez will start against Barcelona at Wembley.
The young Mexican has been a revelation in his debut season at Old Trafford and now looks set to start in the Champions final.
"It's been an incredible season for the boy," the boss said. "Nobody at our club thought for a minute that he'd achieve what he's achieved in his first season.
"Hopefully he continues that way tomorrow night. He's got the temperament, he's got the speed, he's got the movement... he's got all the things necessary to be a good player tomorrow night."
Hernandez's likely inclusion in the manager's starting XI will come as welcome news to many United fans. Sir Alex also banished any suggestion that the Reds would adopt a negative mindset in order to combat a side widely regarded as the biggest attacking threat in Europe.
"We recogise the qualities of our opponents," Sir Alex said. "It's unwise going into a game not preparing your team for how your opponents play - we do that with every team.
"Hernandez has got the temperament, he's got the speed, he's got the movement... he's got all the things necessary to be a good player tomorrow night."
