Rangers have signed up promising French 20-year-olds William Stanger and Antoine Ponroy from Rennes.
Le Guen has a good record with developing young players
Midfielder Stanger and defender Ponroy have no first team experience in France but new Ibrox manager Paul Le Guen believes they can blossom in Scotland.
"I believe we can improve their level and we will try to help them do that," Le Guen told the club website.
"Now they have the chance to develop at Rangers and I'm sure they will progress by working hard every day."
Le Guen had a spell at Rennes before moving to Lyon and is currently in Portugal with assistant Yves Colleu watching the Uefa U-21 Championship.
The French signings follow the recruitment of South African teenager Dean Furman and experienced Czech midfielder Libor Sionko.
