Rondon is currently on loan at Newcastle from West Bromwich Albion.
The 28-year-old joined Newcastle in a deal that saw Dwight Gayle move the other way to West Brom, but both deals are only on loans and as it stands, both players will return to their parent clubs in June.
Rondon has been excellent for Newcastle, having a hand in one goal every two Premier League appearances. Clocking up 22 league outings, Rondon has scored seven times and created four more.
Spanish star Perez, who has played on the wing for much of the campaign, wants Newcastle to sign the 71-time Venezuela international permanently at the end of his current loan.
"I would like him to stay, definitely," Perez said. "He is a great player and makes the players around him even better. Salomon helps us a lot. I want him to stay but it is something to think about at the end of the season.
"In terms of what is going on now, we have to keep going in the same direction, Salomon scoring goals and me trying to assist or score. We are trying to link up as much as we could with [Miguel] Almiron, Salomon and me."
Rondon has scored some important goals of late, equalising against Manchester City in the shock 2-1 win at St. James' Park while providing a goal and an assist in the 2-0 win over Huddersfield.
The Northern Echo claim Newcastle will have to pay £16million to land the former Zenit St. Petersburg striker on a permanent basis, though the inclusion of Gayle in any deal could save Newcastle some money.
Spotrac claim Rondon is earning £60,000 a week at West Brom, and Newcastle may have to offer something similar to land the talismanic striker.
