Goalkeeper Marc-Andre ter Stegen will reportedly be presented to the Camp Nou crowd ahead of Barcelona's potential title decider against Atletico Madrid.
The German international is said to be close to finalising a deal at Barca, despite the Catalan club being handed a transfer ban in April which has since been suspended.
Ter Stegen said an emotional farewell to fans of current club Borussia Monchengladbach in their final home game of the season against Mainz 05 last weekend.
Confirmation of a deal is now imminent and the 22-year-old will be unveiled in Barcelona's colours next week, according to Spanish publication Mundo Deportivo.
Barcelona currently trail Atletico by three points in La Liga.
