Alex Oxlade-Chamberlain finally left premier league teams and in the next season he is going to play for Beşiktaş in Turkey I'm not sure why Chamberlain choose Beşiktaş, because this player is still young he is 29 years old player which means he can play for the top teams in Europe for years but choosing Beşiktaş doesn't make sense for him.
Chamberlain joined Liverpool from Arsenal in 2017 for 42m and he played 146 games for this team, but after 2019 he but injured and he couldn't play in many games for his team.
