Oxlade-Chamberlain was dragged off during the 4-0 thrashing at Anfield but Jurgen Klopp was still willing to spend £35 million on the England worldwide on transfer deadline day.
Oxlade-Chamberlain got first hand of experience of the quality of the current Liverpool side as he was part of the sorry Arsenal team that lost 4-0 at Anfield before the worldwide break.
"I can see him playing in midfield instead of Can or Wijnaldum - but I am intrigued to see if Jurgen Klopp can make him the complete player", Keown told the Mail.
Liverpool have seven matches in 24 games until the next global break, so rotation will be key to maintaining the high-octane pressing game Klopp oversees.More news: Cubs, Brewers set to meet at Wrigley Field

Henderson is also impressed by Oxlade-Chamberlain's versatility, with the Englishman able to operate in a variety of positions, including in midfield and defence.
I hear him out but you also have to bring something yourself.
Wenger also reiterated that he still thinks there's a chance that Sanchez could end up signing a new contract at Arsenal, and that he will stay professional despite the failed Man City move.
"The manager can take me up to the next level - I wouldn't be here if I didn't believe that".
Midfielder Oxlade-Chamberlain could even make his debut this Saturday as the Reds travel to the Etihad Stadium to face Manchester City in a clash of Premier League heavyweights. Did it? I think he (Oxlade-Chamberlain) was not worse than any other player on the football pitch.
Both team's defences have been widely criticised, despite an encouraging start to a campaign that has seen them claim seven points from their first three matches.
