Mahrez was already good at Le Havre (I watched his matches in the French Ligue 2), but unfortunately the context meant he found success late. In France, they favor physical players. He, like Griezmann, had no future there if they hadn't taken their destiny into their own hands. Mahrez always had his childhood friend as his agent; he wasn't lucky enough to be on Manchester City's radar and play for one of the best coaches in history, with so much talent around him. Otherwise, Mahrez, as soon as he started with Leicester in the Championship at 22, we already saw goals from another planet that reflected all his talent.
I'm not making a comparison between Mahrez and Savinho; this is just to provide some clarification on the beginning of Mahrez's career.
