England beat Nigeria 2-1 in a friendly.
Adding to Sterling's woes, the 23-year-old endured criticism for unveiling a new tattoo of an M16 assault rifle on his calf that he said was a tribute to his father, who was shot dead when the City star was a child.
A rapid counter-attack saw Sterling sent scampering into the box by Young, only for the former Liverpool winger's decision-making to let him down as he failed to pick out a team-mate.
Sterling, who also apologised to his England teammates for arriving late to the team's training camp due to a mix-up with flights, has been supported by multiple figures in the game amid the press scrutiny.
Southgate said England had failed to work out how the visitors had changed their approach at half-time, something that might cost them dearly if repeated in Russian Federation.
But Southgate gave no clues as to who would start in goal for England with Jack Butland, Jordan Pickford and Nick Pope the three goalkeepers in the World Cup squad. The most important thing I do in the next six weeks is protect the players.
"We know what we want to see in that area and we're clear on what we think".
The game is being played at Wembley, shown on ITV, and people on social media are going insane over their gorgeous design.
England have been pitted in Group G with dark horses Belgium, Tunisia, and debutants Panama but fans are sceptical about the country's chances following a disastrous 2014 campaign.
Nigeria scored early in the second half in part thanks to England dropping back, and Wright said that was a "worrying" sign heading into the finals in Russian Federation. "I wouldn't necessarily say that that was the side today that starts against Tunisia, but clearly, it wouldn't be far away".
"I should have scored, there was one stuck under my feet and one where the ball was a bit more in front of me and I had to check back, but that's how it goes".
"The first half we felt comfortable, moved the ball quickly and dominated but a lack of concentration early in the second half let us down".
However, the second half was a different story entirely, as England struggled to impose themselves on the game again after Iwobi's goal.
