The 29-year-old has signed a pre-contract agreement with the Scottish club after flying to Glasgow for talks on Saturday. "I have watched Pršo many times this season," said Rangers manager Alex McLeish. "He is very direct and he has a great presence which is just what we need. I am absolutely delighted to have signed a player of his calibre."
Pršo has figured prominently in Monaco's run to the Champions League final, scoring seven goals including four in the 8-3 victory against RC Deportivo La Coruña in November.
"Rangers welcomed me in an extraordinary way," said Pršo. "I immediately had an excellent rapport with the manager and it became clear that I would sign." The forward's coach at Monaco, Didier Deschamps, added: "I feel mixed emotions. On the one hand, it's a good deal for him, on the other
I've lost someone who often proved decisive for us."
Rangers, who trail champions Celtic FC by 16 points with two games left after losing 1-0 to their rivals on Saturday, have already started rebuilding for next season's Champions League campaign. McLeish has also signed AJ Auxerre defender Jean-Alain Boumsong, Livingston FC's Marvin Andrews and midfield player Alex Rae from Wolverhampton Wanderers FC on pre-contract agreements.
