The 58-year-old won the competition with Argentina in 1986 and has been recruited by the national team of the Central Americans, who will play in the competition for the third time, to pass on experience and advice to the players.
And Mario Faraj, vice-president of Diunsa, the company that sponsors the Honduras team, said that coach Luis Fernando Suarez "asked if it was possible to bring Valdano as team motivator", he told Medio Tempo.
"We made arrangements and we did."
Faraj added that it "wasn't easy [because of] commitments he has with a television company to discuss the Champions League final, but in the end he accepted [the offer] with pleasure.
"Valdano will work with players on the mental side of things as well as football. He is happy to share his football experience."
Honduras have been drawn in Group E, alongside Switzerland, Ecuador and France, against who they begin their campaign on June 15.
