According to Pat Nevin of the Radio 5 Live, the Three Lions' World Cup squad isn't even considering the current form of the player.
The man who has not scored for the club since August was taken out of the game just after the hour mark.
Before the trip to the south coast, Blues boss Graham Potter defended his recent performances, but former Blues winger Nevin said that he was having a really, really bad time.
The 59-year-old said that Graham Potter has gotten the best from every player since he has been there.
He won't be considered for the World Cup if he keeps playing the way he is.
After the defeat at Amex Stadium, the lowest ranked player in the online player rater was Sterling.
The final squad for the World Cup will be submitted by the 13th of November.
His three goals at Euro 2020 earned him a place in Uefa's Team of the Tournament.
The forward was not responsible for the defensive horror show on the south coast, but he still had a bad day.
In the first half, only Kepa Arrizabalaga, who was forced off at half-time with an injury, touched the ball more than any other player.
He gave away the ball more than any other player.
Potter has used the former Manchester City player in numerous roles since his appointment, despite the fact that injuries to players such as Kalidou Koulibaly and Reece James have made it hard for him to acclimatise to life at a new club.
Potter said that he has flexibility, ability and quality to play in a number of positions. You are always trying to find the right balance.
We can do better as a group. Individuals will benefit if we do better as a group. The work is located at that location.
