Brendan Rodgers is delighted to have Luis Suarez at his disposal and admits Liverpool cannot afford to lose the striker.
Rodgers added: "He's in his most productive period. Luis has scored 10 goals so far and it took him until February last season to get to that many.
"I wouldn't swap him for anyone. This is a guy whose energy is relentless - he is a defender's nightmare.
"We have one of the best strikers in the world in Luis and we are very grateful for that.
"He's up there in that one per cent of world-class strikers and there's no team in the world that wouldn't want him."
