Tottenham's Vincent Janssen
For 55 minutes Tottenham were second best at Goodison Park.
Unable to deal with Everton's movement and energy, the visitors were nullified in their quest to find an equaliser with Golden Boot winner Harry Kane's post-Euro 2016 hangover on show for all to see.
In the past, Mauricio Pochettino has been criticised for bringing on his substitutes too late to change the game, but even the Argentine could see that something had to give.
Off came Eric Dier and on came summer signing Vincent Janssen and within a matter of minutes, Spurs were level.
The £17m signing wasn't directly involved in Erik Lamela's goal, but it was his introduction that changed the momentum of the game which swung firmly in the visitors' way.
Nowadays it's considered unfashionable to play with two strikers at the same time, ill-thought of as a throwback to the past and an outdated tactic.

But on Saturday it transformed Tottenham allowing them to get a foothold against a stubborn Everton team who had to retreat further into their own half.
Dropping Harry Kane deeper to play off Janssen allowed the England international to see more of the ball and despite his canny trait of finding the back of the net, is criminally underrated as a playmaker and creator of attacks.
31 goals last season and 27 Eredivisie goals in 34 games isn't a fluke for Janssen. He almost had a dream debut, but for a superb stop from Maarten Stekelenburg from six yards to justify his appearance from the bench.
One of the problems from Tottenham's stuttering finish last season was that a lack of rotation really hurt the likes of Christian Eriksen and Kane who were running on fumes unable to give any more than what they provided.
Kane in particular, started every single Premier League game last season having spent nearly the entire season as the club's sole striker, with Pochettino's insistence that Heung-min Son can play up front failing to convince anybody who saw the South Korean play there.

For the first time since his arrival from Southampton, Pochettino has a credible striking option in Janssen.
He's not going to switch to 4-4-2 anytime soon but the opportunity to play Janssen, drop Kane deeper, rest one of Dele Alli or Eriksen in attacking midfield would go a long way in maintaining Spurs' energy levels, not to mention provide a bit more potency in attack.
It takes the pressure off of Kane to find goals by giving him a talented strike partner and potentially allows the 23-year-old to be subbed for a much-needed rest every now and again, which is absolutely vital if Spurs want to challenge on all fronts.
Against Everton, Spurs looked dominant and in control with two strikers on the pitch complimenting each other nicely, showing that in the world of aces, sometimes two of a kind is the best hand to play.
