sounds like the clutch pedal assembly is on its way out. these systems consist of a master cylinder, slave cylinder and hydraulic hose and are a sealed unit. You can buy a replacement on ebay for about £250 easy to replace once you have removed the the dash board to access the top of the clutch pedal where the master cylinder is located (big job). the fulcrum lever on the side of the gear box where the slave cylinder rod engages siezes up and causes the premature failure of the clutch pedal. RENAULT will want £1000 to do it. good luck
