Real Betis veteran Joaquin is eager to work with new signing Giovani Lo Celso.
The Argentine was a deadline day arrival from PSG, joining on a season-long loan.
Joaquin said, "I think he's a very interesting player.
"Technically, he's a great footballer. I have not trained with him yet but I was told a lot of good things about him."
Lo Celso can sign permanently with Betis for €25m.
