U20s set to open up French
Coach Nigel Carolan will be wary of France's Jekyll and Hyde outings in the first two rounds at Donnybrook.
They were ripped apart by England 59-17 in Exeter and tore down Scotland 36-8 in Grenoble.
It is all the more reason for Ireland to concentrate on what they do best.
"The French bounced back well from their defeat to England to win convincingly against Scotland.
"We have a big challenge ahead of us," warned Carolan.
"However, with the quick surface in Donnybrook, along with playing in front of our home fans, the players are looking forward to getting out there and are looking to put in a good performance."
The introduction of out-half Bill Johnston, centre Tommy O'Brien and full-back Robert Lyttle might strengthen the back division. Second row Jack Regan, son of former Offaly hurler Dáithí, is not short of admirers within Leinster and Marcus Rea earns his first start.
Ireland: R Lyttle; J Larmour, T O'Brien, C Frawley, C Nash (capt); B Johnston, J Stewart; J Conway, T McElroy, C Connolly, J Regan, O Dowling, M Rea, P Boyle, C Doris.
France: P Buros; F Fartass, P Barassi, T Dachary, W Iraguha; R N'Tamack, A Retiere; A Roumat, J Ruaud, D Crétin, M Capelli, F Verhaeghe (capt), T Laclayat, E Fourcade, K Tougne.
