Suarez had decided to leave Anfield and was keen to complete a switch to the Gunners, who upset Liverpool officials by submitting a £40 million + £1 offer for the Uruguayan striker.
The £1 was added in the belief that it would activate the release clause in Suarez’s contract.
Despite this, Liverpool refused to allow Suarez to enter talks with the north London outfit.
The Merseyside club’s owner John W. Henry, meanwhile, posted the memorable tweet: "What do you think they're smoking over there at the Emirates?”.
Several months later, after winning back the hearts and minds of the Liverpool supporters through his brilliant performances, Suarez ended up signing a new four-and-a-half year contract with the Reds.
Seven months after putting pen to paper on that deal, Suarez left Liverpool after Barcelona agreed to pay a cool £75 million for the world-class South American - a fee which, in hindsight, now looks a relative bargain.
Firmino's bizarre anti-Arsenal clause
Liverpool have clearly learned their lessons because, according to the latest Football Leaks releases in Le Soir, Roberto Firmino’s current contract contains a bizarre anti-Arsenal clause.
The Brazil international, who completed a £29 million switch to Anfield from Hoffenheim in the summer of 2015, is understood to have a €98 million (£82 million) release clause in his contract.
The report - which has been brought to our attention by Goal and the reliable Belgian journalist Kristof Terreur - states Firmino can be purchased for the aforementioned price “if the interested club is not Arsenal”.
It seems the Reds haven’t forgiven Arsenal for submitting what they deemed - and still deem - as an insulting offer for Suarez.
Firmino has become a key player under Klopp
Firmino has established his status as the Reds’ first-choice centre-forward, ahead of Daniel Sturridge, under Jurgen Klopp.
While his goalscoring record is hardly spectacular - 17 in 64 in all competitions - it’s his all-round contribution and work ethic which has impressed not only Klopp but also the Liverpool fans.
