Cape Town - Liverpool boss Jurgen Klopp is convinced that Alex Oxlade-Chamberlain will make an impact for the club, after a low-key start to his career at Anfield.
The England international ended a six-year association with Arsenal when he joined the Reds in a £35 million deal on transfer deadline day, but hasn't clicked yet for his new team.
Oxlade-Chamberlain came in for criticism after making his first start for Klopp's side on Tuesday when they crashed out of the EFL Cup following a 2-0 defeat to Leicester.
The Merseysiders have lost all four games that the 24-year-old midfielder was involved in, but Klopp revealed a calf niggle has affected his performances and believes he will come good.
When asked about the poor reviews for his new recruit, the German said in his pre-match press conference ahead of Saturday's rematch with the Foxes: "That's the world of football, it is quite quick with all that stuff. I'm not a aware of it [the criticism] but I can imagine.
"Ox had a few good really, really good situations and a few unlucky situations. I thought he did well in them moments where you could see he tried to adapt to the style of play and all that stuff.
"He had a little problem with his calf - it's not an injury but a little problem - and we all have to get used to this and manage this a little bit better.
"It's the first game from the start and nothing else. We lost, he didn't make his best game in his life so then people probably ask what impact he can make. But I'm not in doubt about this."
