One of the main reasons for this is his limited playing time. Since joining Chelsea, Sterling has only made 19 appearances in all competitions, and his goal-scoring record has been disappointing, with just one goal in all competitions last season. Even at Arsenal, where he had a successful loan spell, Sterling's output was not as high as expected, with just one goal in all competitions.
So, what's behind Sterling's struggles at Chelsea? One reason is his lack of confidence, which may have started when he lost his place in the national team. Despite being given plenty of opportunities to regain his form, Sterling has failed to deliver, and his pass completion rate has been inconsistent.
Another factor is Sterling's willingness to beat players with the ball. In the same three-year period, he only took on his opponent 88 times in all competitions and played just 22 through balls to a teammate. Perhaps most worrying of all is that he was unable to complete any passes when under pressure.
Ultimately, football players are only at their best when they're enjoying their football, and it's clear that Sterling isn't doing that anymore. The less he plays, the more rusty he'll become, and with two years still left on his Chelsea contract, there's a big decision for him to make.
One option could be to take a step down and move forward, perhaps as soon as next January. It might mean swallowing his pride, but it could be the best way for Sterling to resurrect his fast-fading career.
Accepting that his best years are behind him could be the reset point Sterling needs to motivate himself for what's ahead. If he can admit that to himself and use it as a tool for improvement, there's still an opportunity for him to revive his career and make a lasting impact on the game.
For now, it's clear that Sterling's time at Chelsea has not been the success he had hoped for. But with two years still left on his contract, there's still a chance for him to turn things around and make a comeback.
