An old-school target man, Carroll will provide a stern physical test for Tottenham's centre-back trio, but played through the middle, it's likely he'll find himself one-on-one with Davinson Sanchez, the middle of the back three, more often than not.
Slaven Bilic stuck Carroll up top, pushed Hernandez wide, and West Ham inevitably altered its approach.
Tottenham travel to the London Stadium on Saturday to face West Ham, against whom Dier made his debut three years ago and scored the victor in a 1-0 victory. And when Carroll lost them, West Ham's high defensive line was exposed.
Bilic has won all three of his home managerial meetings with Mauricio Pochettino by a single goal to nil, including two with West Ham and one while in charge of Besiktas in the 2014-15 Europa League group stage.
"Spurs have picked up maximum points on their travels this season. But it is a great result", Kane said after the game.
Carroll, who cost £15million from Liverpool, has missed 114 matches through a catalogue of injuries since he signed for the Hammers in 2012.
"Because if we are talking about his contract, the question mark about him is his fitness, about how much he is available during the season". A record buy at West Ham, a lot more was expected and it's safe to say that he has failed to replicate any of the good stuff that he pulled off at Stoke.
Bilic is an admirer of what Pochettino has achieved in North London, and expressed sympathy for the problems his counterpart faces in making Tottenham more comfortable in unfamiliar surroundings.
As Bilic acknowledged, West Ham can not rely on Tottenham's problems with playing in wide-open spaces to pull off a third successive home win.
The Hammers tend to raise their game against their fiercest rivals and Pochettino has warned his side they must be up for the fight. Harry Kane was unlucky not to score a first-half hat-trick as the Hammers back three struggle to contain him.
