The former Tottenham Hotspur manager spoke to reporters ahead of his side's trip to White Hart Lane on Sunday.
The 67-year-old was speaking to the press ahead of his side's Premier League clash with Tottenham on Sunday, stating that he expects an attacking performance from Mauricio Pochettino's side.
But his next words, while respectful to the club he used to manage, hinted that they performed better during his time in north London.
“They’re a top side who should be pushing for the top four, like they were when I was there."
Redknapp was sacked, of course, after guiding Spurs to fourth place in the league but missing out on Champions League qualification, as Chelsea had stolen their spot in the competition by winning it the previous year.
The season before, Tottenham finished fifth under Redknapp while also reaching the quarter-finals in Europe, having finished fourth the campaign before that.
Andre Villas-Boas followed the 67-year-old at White Hart Lane and guided them to fifth before being sacked the next year, with Tim Sherwood then also leaving the club after half a season in charge.
“I shouldn’t get a bad reception but that doesn’t concern me," the QPR boss continued.
“All I’m worried about is my QPR team going there and putting on a performance and hopefully getting all three points."
Spurs won their opening Premier League clash last weekend and also beat AEL Limassol 2-1 in Europa League qualifying on Thursday.
