Wright, speaking on the Stick to Footballpodcast, made it clear that Sterling is running out of chances to prove himself at Arsenal.
"For Kai Havertz to get an injury at this stage is just devastating," Wright said. "You can pull a hamstring, but something has gone wrong if it's ruptured to the point where he's out for the season. He's played a lot of games for us, and Mikel Arteta would be thinking that he needed to get a player in January. The opportunity that has arisen for him [Sterling], this is the time where he should buckle down and say, 'I have to make this work'.
"Otherwise, he'll go out with a whimper. The last time I saw him come on and do something in a short space of time, was against Manchester United – that’s what you want to see from him, just come on and try to make something happen. The fans are hoping as well – you can hear their groans, so you feel that he's in that place where if he doesn't do anything positive, he can hear them coming – and that's not a great place to be."
