Monaco are the surprise package in the semis and coach Leonardo Jardim has moulded a thrilling team around the resurgent Radamel Falcao and the break-out teenager Mbappe, whose goals saw off Man City and Dortmund in the last two rounds.
Mbappe, 18, who has been compared to Thierry Henry at the same age, delivered another crucial goal at the weekend as Monaco close on their first French title since 2000.
It was his 14th league goal of the season.
Monaco’s clash with Juventus will be a study in contrasts: the tyros against the Italian champions whose defence is backed by the inspirational Italy captain Gigi Buffon, 39, in goal.
Influential midfielder Tiemoue Bakayoko broke his nose in training on Friday, but looks to be the only key player in doubt for Monaco.
Beaten 2015 finalists Juve were held to a 2-2 Serie A draw at Atalanta this weekend after conceding a last-gasp goal.
“We’ll learn from our mistakes and be mindful for Wednesday’s match,” said coach Massimiliano Allegri, who will be looking to Argentine striker Gonzalo Higuain to fire them into the June 3 Champions League final in Cardiff.
