Now the question over who will join Oxlade-Chamberlain at Liverpool hangs in the air, with Van Dijk's enduring links with a move to Anfield continuing throughout this summer.
"He's got huge talent, he's a decent lad, but I think he has three or four areas of his game that he has to significantly improve - the biggest being concentration".
With no Champions League football and chances of a Premier League title slipping away before the leaves even begin to darken, hope at Arsenal is increasingly disappearing.More news: Watch Jordan Vogt-Roberts' Destiny 2 Trailer

However, Carragher went on to question whether Oxlade-Chamberlain will be able to fulfil his ambition of playing regularly in the centre of midfield in Klopp's squad. "Since then I have followed him and when I heard it may be possible to sign him I didn't need to think twice".
This is believed to be the reason for Jurgen Klopp bringing the player from London to Liverpool.
As far as the attack is concerned, Liverpool already have star players like Firmino, Mane, Sturridge and summer signing Salah up front and all of them have found the net for the Reds this season.
"I watched the boys in the first few games of the season and they've got a lot of energy", Gibbs said in comments published on the West Brom website.
Oxlade-Chamberlain was deployed in the right full-back position for the match where he struggled to make an impact and he was eventually substituted after an hour.
"I think he definitely strengthens the group and the team", Gerrard said. "But Liverpool will take him out of his comfort zone".
