Oxlade-Chamberlain moved to Liverpool from Premier League rivals Arsenal on transfer deadline day.
Former Celtic and Chelsea striker Cascarino, who now works as a pundit for talkSPORT, has a theory why the ex-Southampton man chose Liverpool ahead of the defending Premier League champions.
“Oxlade-Chamberlain is a direct player with blistering pace, who wants to drive forward,” Cascarino wrote in The Times. “He can’t defend.
“He can hassle and press, but I think he knows that his strength is not being out wide, where he is required to chase back.
“That’s why he turned down Chelsea; offensively, he is better than Victor Moses but he cannot defend like he does. He is simply not a natural at it.”
Oxlade-Chamberlain is a good and talented player, and at just 24 years of age, the Englishman is still very young.
Liverpool manager Jurgen Klopp is a very good coach, and the England international can only improve under the German.
The Merseyside outfit have made a strong start to the 2017-18 Premier League campaign and will be aiming to challenge for the league title.
