The club is confident that Wissa will stay with them for the upcoming season. They are preparing for him to train with the rest of the squad and be part of the team for their first Premier League game against Nottingham Forest.
This decision comes after the departure of Bryan Mbeumo, who joined Manchester United for £71M. With Wissa having one year left on his contract, a deal to transfer him to another team seems unlikely under the new manager, Keith Andrews.
Newcastle United have reportedly entered talks with the agent of RB Leipzig's striker, Benjamin Sesko, which suggests that Wissa will not be joining them in the near future. His dream of playing in the Champions League may have to wait.
Brentford will fly back to London on Tuesday and prepare for a friendly match against QPR on Saturday. This will give Wissa a chance to improve his fitness and prepare for the upcoming season under the new manager.
