PSG coach Unai Emery has spoken of clashing with Steven N'Zonzi at Sevilla.
The Frenchman has been outstanding for Sevilla this season.
"About a year ago, I kicked him out of a training session because he didn't want to train. Later, he came up to me and said he wanted to leave," Emery told El Pais.
"So I told him: 'Take three days off; nobody will know. And come back on Monday. Forget about everything and when you come back we'll talk'. He wanted to leave because he didn't feel happy. He wasn't settled in Seville, the city. So he came back on the Monday and I asked him: 'And...?'. He replied: 'I'm staying!'.
"A little later after that, from December onwards, he started performing to a high level. He's confirmed it this season with [Jorge] Sampaoli."
