Grzegorz Krychowiak is having a medical at West Brom ahead of a loan move from Paris Saint-Germain.
The midfielder, who cost PSG £34million when he signed from Sevilla last year, was convinced by manager Tony Pulis to join the Hawthorns club for the rest of the season.
It follows the arrival of Oliver Burke from RB Leipzig, another player convinced to swap the Champions League for a spell with West Brom.
Krychowiak, who has struggled to settle at the Parc des Princes, played the entirety of Sevilla's Europa League win over Liverpool in 2016.
