The Spurs legend has been hugely impressed with the Belgian.
The Belgian has played a big role in helping Spurs challenge for what would be their first league title since 1961, forming a fine centre-back partnership with compatriot Jan Vertonghen and, more recently, Kevin Wimmer.
Tottenham sit second in the Premier League table, five points behind leaders Leicester City with eight games to go.
The likes of Dele Alli and Harry Kane have flourished in an attacking sense, but club legend Hoddle says a defensive solidity has been the most impressive aspect of their title tilt.
"We've been impressive with the two centre-halves, Eric Dier and goalkeeper Hugo Lloris. On Saturday, there was a looseness which I've not seen most of the season," he told The Mail.
"But there has been a solid base in Jan Vertonghen and Toby Alderweireld, who I think is the best defender in England."
It is a shame that Spurs' defence could not be as solid in Europe as they are domestically, with Borussia Dortmund all but eliminating them from the Europa League.
Mauricio Pochettino's side go into tomorrow's last-16 second leg at White Hart Lane knowing they must score at least three times to keep alive their quarter-final hopes, with Dortmund winning 3-0 last week.
Still, going out of Europe might help them concentrate on winning the Premier League, with eight league matches to go.
