Sir Alex Ferguson’s men face Pep Guardiola’s Catalan kings in the showpiece event for the second time in three years after Barcelona prevailed 2-0 in Rome’s Stadio Olimpico in 2009.
Both sides will be desperate to triumph at this year’s final venue, with Wembley the setting for their first European Cup victories, in 1968 for United and 1992 for Barca.
“Make sure you’re within touching distance on his first touch,” he said. “If you let him get a head of speed and start running at you, you’re in trouble.
“As the ball’s coming to him you’ve got to be close enough to be able to get up to him and try and not let him turn. If you let someone like that turn and run at you, you’re in their world and they’re dictating what’s happening, whereas if you keep them with their back to the goal then you’re dictating to them.”
Midfielder Carrick is also set to start Saturday’s showdown having featured in both the 2009 final defeat to Barca and the victory over Chelsea in Moscow the year before.
“If they have someone playing off the front like Messi, you want to push them wide to cut them space from playing in the middle," he told FourFourTwo Performance.
“If their biggest threat is out wide you have to try and show them to the other side."
