The 29-year-old has penned a four-year deal that runs through until June 30, 2023 and will become the eighth Senegalese player to turn out for the Parc des Princes side.
Gueye spent four successful years in England, having started his professional career in Europe with Lille, where he played 176 times. From there, he moved to Aston Villa and subsequently Everton, spending a single year at Villa Park and three at Goodison.
His move to Paris, though, will give him the chance to play in the Champions League and he insists he’s excited to be joining the PSG project.
“I’m immensely proud to sign for Paris Saint-Germain,” he told the Parisian club’s official website.
“After focussing on the AFCON with Senegal, I wanted to give a new boost to my club career by joining Paris Saint-Germain, one of the most structured and ambitious sports projects in Europe.
“I’d like to thank the directors, the coach and his staff for the confidence they have shown in me. I will do everything to justify the faith they have shown in me and to integrate into this talented squad.
