Liverpool have beaten Chelsea to the signature of Arsenal midfielder Alex Oxlade-Chamberlain, in a deal believed to be in the region of £40m.The 24-year-old was in the last year of his contract with the Gunners and had conveyed his decision to the North London outfit that he will not be extending his contract. Chelsea were the first club to agree a fee with the Gunners, however, Chamberlain couldn't agree personal terms with the Stamford Bridge outfit.This provided Liverpool with the window to sweep in and complete the signing of the English international, making him the first player in Premier League history to move from Arsenal to Liverpool.Twitter, as you would expect, didn't hold back following the announcement by the two clubs:The confirmation...Welcome, @Alex_OxChambo! ? pic.twitter.com/joYm7hvK3m— Liverpool FC (@LFC) August 31, 2017Alex Oxlade-Chamberlain has signed for Liverpoolhttps://t.co/VYn2yCcDcQ— Arsenal FC (@Arsenal) August 31, 2017Our new signing in a nutshell. ? pic.twitter.com/Kld6LgNPif— Liverpool FC (@LFC) August 31, 2017Ohh, the humour...EXCLUSIVE: #AFC fullback Hector Bellerin has handed in a transfer request following the departure of secret lover Oxlade-Chamberlain to #LFC— Simon Rowntree (@SiRowntree0161) August 31, 2017Looks like Arsenal fans will not miss him...Liverpool complete the signing of Alex Oxlade-Chamberlain he can produce more performances like this #Deadlineday ? pic.twitter.com/UwnRlJscu0— Ali (+_+) (@TvvitterGod1) August 31, 2017Alex Oxlade-Chamberlain kissing last trophy of his football Career.. pic.twitter.com/3NsDS79RqM— Gooner Nick (@NickVann1987) August 31, 2017Ohh Southampton...Oxlade-Chamberlain proving that once you've played for Southampton you will still end up at Liverpool somehow.

One year left, injury-prone, no fixed position & no end-product. #afc— Sam (@samuelJayC) August 30, 2017WHY WERE TWO TOP TEAMS WILLING TO PAY FOURTY MILLION POUNDS FOR ALEX OXLADE CHAMBERLAIN— Paddy (@VieiraPaddy) August 30, 2017OUCH!I'm surprised Liverpool are trying sign Oxlade-Chamberlain after recently getting rid of Jordan Ibe. Basically the same player.— Woz (@wozthegooner) August 30, 2017What I don't get about Chamberlain is he's 24, played about 3 games in central midfield, and now thinks he's Pirlo. Odd. #AFC— Daniel Cutts (@Journo_Slash) August 30, 2017The love between the two...EXCLUSIVE: #AFC fullback Hector Bellerin has handed in a transfer request following the departure of secret lover Oxlade-Chamberlain to #LFC— Simon Rowntree (@SiRowntree0161) August 31, 2017Hahaha...Can someone ask Chelsea to bid for Van Dijk so we can snatch him off them like we did with Oxlade-Chamberlain?— DaveOCKOP (@DaveOCKOP) August 31, 2017The decision making, though!Typical Oxlaide-Chamberlain. Gets himself into an ideal position, then mucks it up with the final decision. https://t.co/Z4T3ZVF4R9— Jay (@allinthepass) August 28, 2017
