Hasselbaink knows a thing or two about scoring goals for Chelsea, and the Dutchman has named the two players he would like to see at the club next season.
"Chelsea are in desperate need of proven firepower so I would love to see them make a move for Lewandowski or Icardi this summer," said Hasselbaink to reporters.
"Icardi would be my preference as I'm a little bit worried about Lewandowski's age.
"I think Icardi is a more realistic target while also being more likely to adapt to the Premier League.
"Lewandowski is a superb striker but he is the wrong side of 30 and we have seen with Higuain that England is not an easy place to come at that stage of your career."
