The truth that the Premier League will be a place he misses has some truth to it and joining one of those teams could be a great option. However, I don't see that Arsenal or Chelsea will be interested in recruiting him considering he is getting older and the two London teams are currently focusing on overhauling the squad which will all be filled with players under 30 years old.
When Sadio Mane joined Bayern Munich they were expecting to see a player like Lewandowski become a top scorer and since Sadio Mane scored many goals and had a good performance in Liverpool we were right to expect something like that from Sadio Mane but it seems he couldn't show the good performance we wanted to see from him and that's normal to see him even leaving Bayern Munich.
Mane did not perform well. Mane could not show the expected effect in a team like Bayern Munich that scored a lot of goals. Sometimes, no matter how good the team you transfer to, you may not be successful. There was a similar situation in Mane.
I would love to see Mane at Chelsea. Because Chelsea were not successful last season and are working to strengthen their squad next season. Chelsea can sign a player who knows the EPL. Mane is one of these players.
It is very difficult to find a player who can perform like Lewandowski did at Bayern Munich. Mane could not do what he wanted in the face of great expectation.
