The Santos Laguna coach "would be sad to lose a player like him" but wants to do what is best for the 29-year-old striker.
What's more, the Portuguese manager would heartily recommend the Mexico international if European coaches do come calling.
"If they contact me (I would recommend him)," said Caixinha during a press conference Friday ahead of Sunday's playoff quarterfinal against Queretaro. "It would be sad to lose a player like him, but there is a relationship with the players that I like.
"They help me because they are the ones that help me win on the field, so I have to help them, too."
The Santos coach went on to stress that Peralta will not be affected by rumors about a potential departure to Europe and the he has an important job to do with Los Guerreros in trying to win the Apertura title.
"He has the humility to know that he's here right now," said Caixinha, before going on to praise the forward: "He has the faculties (to play in Europe). I see him playing in a big club with a lot of ease."
Caixinha also turned his attention to the game against Queretaro, pointing out that although the Gallos Blancos may be underdogs going into the clash against Santos, they didn't concede a goal in nine of the 17 regular season matches.
