The former Tottenham Hotspur boss has been discussing the north London side's back four.
Harry Redknapp believes Jan Vertonghen was 'average' for Tottenham last season, according to his regular column in the London Evening Standard.
Indeed, the former Tottenham boss has hailed the summer arrival of centre-back Toby Alderweireld, especially for the effect it has had on Vertonghen.
The 28-year-old looks much improved this time around, in Redknapp's eyes, but he feels the Belgian's form was below part last campaign. Alongside Alderweireld, it has been a different story for the experienced defender.
Redknapp told the Standard: "They have got high-class individuals throughout the team now. Toby Alderweireld has made a big difference in defence.
"I’ve always thought Jan Vertonghen is a very good player but he was looking average last year as Spurs struggled to find someone to play alongside him.
"They chopped and changed all the time but now the back four picks itself and Vertonghen looks much more solid with a settled partner alongside him."

As Opta stats show, the Belgian averages more tackles and interceptions per game this season, boasting a slightly improved passing accuracy, as well.
The fact the campaign is only 13 games long so far perhaps doesn't allow for too much reflection of Vertonghen's improvement, of course, as he averages less headers and clearances per game.
Beyond the stats, the Spurs centre-back's upturn in form has been very notable indeed. And, even when the 28-year-old has erred, Alderweireld has been alongside him to clean up.
Next up for Tottenham is another London derby: a crunch clash against Chelsea on Sunday afternoon.
