Both Marseille players. Imbula is a powerful box to box midfielder while Mendy is an attacking leftback. Both exploded with Bielsa this season; Imbula was actually one of the best midfielders in the Ligue in the first half of the season. Both could turn out to be decent prospects IMO. Imbula is a box to box midfielder that is physically very strong, and he's quite a good dribbler too, he's quite similar to Yaya Toure in playing style, minus the creativity in the final third, but he's mostly similar in how he runs past defenders using his physique very well, he faded away at the end of the season though, so he's yet to have a full good season. As for Mendy, he looks very promising, the only reason more people haven't heard about him was because Amavi and Kurzawa had excellent seasons. The biggest criticism I'd have for Mendy is that he doesn't seem interested in defending, because going forward he's really good; very fast and is actually a decent crosser of the ball.
Speaking of Ligue, where's @Aush lately.
