Orlando Villarreal revealed: "Let me be clear on this issue, an approach has been made by us to Manchester United for a scout to be invited to observe Frickson, that's how it started. We are convinced that the player has a great future.
"For some time we've been working on a move to Europe for the player."
Villarreal added the Boca clash would represent an ideal opportunity to see the Ecuador defender in action against top drawer opposition.
