Holloway believes that QPR need to sign a striker like their current manager Jimmy Floyd Hasselbaink in the summer transfer window.
The former Rangers manager has also claimed that the London outfit have not replaced Charlie Austin.
“I'm not entirely sure about the QPR squad yet,” Holloway told Sky Sports while predicting an 11th-placed finish for QPR in the Championship this season.
“Jimmy Floyd-Hasselbaink is the right man for the job but they haven't replaced Charlie Austin. It's okay to play in a certain style but you need to have a striker like Jimmy to bang in the goals.”
Austin left QPR for Premier League club Southampton in the January transfer window.
According to The Guardian, the Saints had to pay Rangers a transfer fee of £4 million to secure the services of the 27-year-old striker.
Austin scored 18 goals and created 23 chances in 35 Premier League appearances for QPR during the 2014-15 campaign.
The Englishman scored 10 goals and created 17 chances in 16 Championship matches for Rangers last season before moving to Southampton in the January transfer window.
The former Burnley striker scored one goal and created one chance in seven Premier League matches for the Saints during the second half of the 2015-16 campaign.
QPR will be aiming to finish in the top six of the Championship this season.
