According to sources, Henderson's wages are the main reason behind Ajax's decision to let him go. As a result, Sunderland, which is Henderson's hometown club, is keeping an eye on the situation.

Henderson began his professional career at Sunderland before joining Liverpool. He is now back in the England national team and has been assured by England coach Thomas Tuchel that he can keep his place in the team if he continues to play consistently.

However, it's likely that Henderson would have to accept a significant salary reduction if he were to join Sunderland. This could be a challenging decision for him, but it may also present an opportunity for him to return to his hometown club.
