Performances in attack from the likes of Nacer Chadli and Erik Lamela drew most of the headlines and plaudits. The often-scintillating Spurs display was built on the less-acclaimed dominant work Vertonghen and his fellow defenders did stifling QPR's own forward men.
Of those other defenders, new signing Eric Dier has certainly stood out this season with his assured manner at both ends of the pitch. Younes Kaboul and Danny Rose both played well this past Sunday, too.
The sight of a sharp, motivated Vertonghen playing so well was perhaps most positive here for Spurs.
Hugo Lloris' continued reliability in goal and the creativity of last season's main man Christian Eriksen will be crucial to the progress of Mauricio Pochettino's team this season.
With improvements in defence a must for Spurs to better their 2013-14 campaign, however, it is Vertonghen who is key to any forthcoming success.
