The 36-year old made just two substitute appearances under Kenny Dalglish in 2000 and he is keen to see fellow Venezuelan Miku, on loan from Getafe, get some further chances in the green and white hoops.
"I read that Miku can leave Celtic in the transfer window because he has not been playing often," he told SunSport.
"People cannot make quick judgments on Miku after only ten games at Celtic.
"You need time to adapt to the style and the speed of the game in Scotland.
"The style of the SPL and Spain is completely different. You have to get to know your team-mates. The team has to get the ball to Miku otherwise you are not using him properly.
"I am aware that Celtic's fans will not remember my time there.
"I can summarise my spell there by saying I only played two games and in between a new manager arrived and changed things around.
"Do not make the same mistake with Miku by making any rush decisions. He needs time to settle in Scotland.
"Believe me, if you give him time he will be loved by Celtic's fans because he will start scoring goals."
Miku has made eight Scottish Premier League appearances and scored one goal for a total of 11 outings in all competitions.
