If he does he won't be the first Villeneuve at Le Mans. His uncle, also called Jacques had a go in 1983 driving in, an odd twist, a Sehcar, which to all and intents was a Sauber, his nephews former employer.
Putting Jacques the younger into your car at LM would be not be a bad idea. He has a very good finishing record in both GP and IndyCar before, he is PR savvy and would bring some strong sponsors to a worthwhile team and most important he is pretty quick.
If he where to win he would be one of few drivers to win a world F1 drivers crown the indy 500 and the 24 hours. Shame he never won Monaco.
