Tau signed for the Seagulls nearly three years ago but has seen minimal game time for them. For much of his time under their employ, he played in Belgium on loan at various clubs due to work permit issues.
Then, after being recalled to England in January 2021 after excellent efforts in the Jupiler League, he spent the bulk of the rest of the Premier League season on the bench.
Tau made only three Premier League appearances after he returned to Brighton, and it is speculated that he is on the brink of signing with Al Ahly, where his former Mamelodi Sundowns coach Pitso Mosimane is the boss.
So while Broos has named the forward in his squad for upcoming World Cup qualifiers, he has warned that he wants his players on the pitch rather than the sidelines, especially those in Europe.
Broos told the media on Thursday: "Percy Tau, I hope, I hope he can leave Brighton and that he can go to a (new) club.
"There is talk about Egypt, Pitso [Mosimane] who is in Al Ahly; it should be a very good thing for him because there he has a coach who knows him."
He added: "I hope that the players who are in Europe are playing.
"There are already a few players who changed clubs. Hopefully, for them, it's a good thing and that in their new clubs they can play more.
"I heard the critics already in May when I came here, [asking], 'Why are the players in Europe not selected'.
"I hope that will change and that we can really select players who are playing most of the games in their clubs."
