Jurgen Klopp should sign Pierre-Emerick Aubameyang to take Liverpool to the next level as they defend their Premier League crown, according to Stephen Warnock.
Klopp and Aubameyang worked together for two seasons at Borussia Dortmund between 2013 and 2015.
And with the Gabon international, who has scored 22 goals this season, stalling on a contract extension at Arsenal, Warnock believes Liverpool should pounce to provide competition to Mohamed Salah, Sadio Mane and Roberto Firmino in attack.
This summer will be the last opportunity for Arsenal to cash in on their captain, 31, with his Emirates Stadium contract due to expire in 2021.
Former Liverpool defender Warnock told BBC Radio 5 Live: 'If I was Jurgen Klopp, I'd be going for him with a year left on his contract.
'You're wanting a goalscorer who can either come off the bench and play on a regular basis.
'He will challenge the front three, he doesn't need time to settle, you know he's proven, he knows the manager and the manager knows what he's about.
'Aubameyang will be on big wages, but he won't cost you big money to get him out with a year left on his contract and the age that he's at.
'Would Aubameyang like to go to a club like Liverpool, Manchester City or Manchester United?
'From his point of view, being a squad player at 31, competing for the Champions League, competing for leagues, and he will win some trophies going to one of those three clubs - that's what he wants at the end of his career.
'When you retire, to have that association with one of those clubs, as well as Arsenal, as well as Borussia Dortmund, what a CV you've got then.'
Aubameyang's decision on a new Arsenal contract is likely to depend on whether they qualify for European competition next season.
They are currently seventh in the Premier League table after Wednesday night's 4-0 win over Norwich City - in which Aubameyang scored twice - but remain eight points shy of the top four.
Aubameyang is the joint-top goalscorer in the Premier League alongside Leicester City's Jamie Vardy on 19 goals.
He enjoyed two decent scoring seasons under Klopp when at Dortmund, netting 16 goals in 2013-14 and 25 the following season before hitting greater heights under Thomas Tuchel.
