That’s the sensational opinion of former Newcastle striker Micky Quinn.
Sarah has been in outstanding form for Liverpool since signing from Roma for around £37m last summer.
The Egypt international has scored 22 goals in 26 Premier League appearances so far this season.
Liverpool sold Coutinho to Barcelona for £142m in January, making a huge profit on the £8.5m they outlayed on him.
But Quinn believes the investment boss Jurgen Klopp made in the 25-year-old forward has outstripped any other Reds signing in over a decade.
“Luis Suarez was an unbelievable player, but he came with a lot of baggage – this kid has no baggage,” he told talkSPORT.
