Jese Rodriguez has passed a medical with La Liga side Las Palmas and is set to be unveiled by the club after joining on loan.
The PSG forward has failed to establish himself in Unai Emery's plans this season and sought out a move back to Spain.
His temporary switch extinguishes interest from Middlesbrough, with Aitor Karanka's side linked with the former Real Madrid man.
The Premier League side had agreed terms with PSG but Rodriguez was insistent that La Liga would be his destination.
