Alex-Oxlade-Chamberlain has netted three goals in his last two appearances for Liverpool, but Jurgen Klopp has explained why the midfielder has failed to hold down a regular starting berth.
Chamberlain has only started five games in all competitions this season under the German, with only two coming in the Premier League.
The 26-year-old helped Liverpool defeat Arsenal in the Carabao Cup this week and netted a superb goal on Wednesday, but Klopp insists the player still needs to find rhythm after following last season's injury.
"He has scored, nice, both at Genk, a real stunner on Wednesday, a lot of outstanding moments, but other moments he is not involved, " Klopp said, as per the Mirror.
"We always have to try to reach perfection. He still needs rhythm but that is no problem. He is a long-term project.
"It is good a player thinks he is not at his best. He could think he is because he scored some goals. Quite some space for improvement. That is good.
"Best shape ever before injury? He was exceptional."
