OH Leuven has loaned Brunes to the Polish club Rakow for the season. He has performed well, scoring 9 goals in 23 league matches. Rakow is interested in keeping Brunes and has an option to buy him for 2 million euros. However, this price is considered very high for Rakow, as the most expensive transfer for a Polish club is 2.3 million euros, and Rakow has never paid more than 1.5 million euros for a player. OH Leuven is firm on the 2 million euro price tag.

Jonatan Braut Brunes joined Raków Częstochowa during the summer transfer window on loan from Oud-Heverlee Leuven, with an option to buy. Despite scoring four goals in 16 appearances, Brunes has not fully convinced the coach Marek Papszun and the club officials. Currently, he is closer to leaving Raków Częstochowa in the summer rather than being bought by the club.
