PSG announced the signing of Cameroon striker Eric Maxim Choupo-Moting moments before the end of the transfer window on a two-year contract from Stoke for £13.5million.
He links up again with Tuchel, who oversaw the best spell of his career at Mainz, the forward having spent three seasons with the Bundesliga club before joining Schalke and then Stoke.
He scored five goals in 32 games for Stoke but hadn’t played since their drop to the Championship.
“I am extremely honoured to be signing for this big European club, Paris Saint-Germain,” Choupo-Moting told PSG’s official website.
“I would like to thank the directors and the coach for the confidence they have shown in signing me. I will give my absolute maximum out on the pitch, every day, to show my dedication to my new club.
“Coming to France, a big football country, is a fantastic moment in my career. I will be playing with some extraordinary teammates and I can’t wait to experience the atmosphere at the Parc des Princes!”
The Hamburg-born attacker scored 10 goals in a pair of Bundesliga seasons under Tuchel at Mainz, before moving on to Schalke, where he would 18 times in the league over the next three seasons.
The Choupo-Moting then moved to Stoke on free transfer, where he played in 29 Premier League games, netting five times.
A former Germany youth international, Choupo-Moting chose to represent Cameroon at the senior level and has received 45 caps.
