Veretout - Played regularly for Fiorentina for 2 years, then moved on loan to Roma last season, was a regular starter as they finished 5th in Serie A
Gueye - Became one of the best DMs in the Premier League for Everton for 3 seasons and then moved last season to PSG for £30m, where he has rotated with Veratti, Paredes and Herrera
Gollini - Atalanta's starting GK and has been a part of a team that reached the Champion's League for the first time in Atalanta's history, then got to the QFs and finished 3rd in Serie A this season, which was they're joint highest finish with the 3rd place the year before.
Amavi - Regular starter at Marseille for the past 3 years in which they have finished 4th, 5th and then 2nd (basically like winning the title considering PSG run away with the league every season ) in Ligue 1.
All done pretty well considering some were considered not good enough for the championship.
