Since returning from the 2025 AFCON, where he struggled to impress amid high expectations of him, Mbule has not been a Pirates regular.
Relebohile Mofokeng's top performances as a number 10 have made it difficult for Mbule and January signing De Jong to enjoy regular football.
That could complicate Mbule's chances of making the squad for the 2026 FIFA World Cup.
It could also disturb De Jong's prospects of going to the global football tournament with New Zealand.
