The former Southampton and Leicester boss took over at the club in October, and thinks the decision to sell the youngster to the Gunners was wrong
Saint-Etienne manager Claude Puel is reeling from his club’s decision to sell star defender William Saliba to Arsenal over the summer, despite getting him back on loan.
The 18-year-old French defender joined the Gunners in a £27 million ($34m) deal, signing a long-term contract in north London but heading back to Ligue 1 for one more year to continue his development as a first-team player.
Only three sides bettered Saint-Etienne’s record of 41 goals conceded in the French top flight last season, with Saliba featuring heavily in the second half of the campaign.
