England qualified for the round of 16 in this year's FIFA World Cup by hammering Central American minnows Panama 6-1 in a Group G clash in Nizhny Novgorod on Sunday. It was arguably an even more one-sided encounter than hosts Russia's 5-0 thrashing of Saudi Arabia in their World Cup opener.
First of all, just in case England fans are in danger of getting carried away, let's be quite clear about one thing. Thrashing a feeble Panama side does not mean that the Three Lions are now serious contenders for this year's World Cup. Yes, it was England's most emphatic win in the finals of any major tournament in history, but their clash against Belgium on Thursday will be a far more meaningful test of their potential.
Nevertheless, in the past, England have struggled against teams whose primary objective was to contain them. This time, against a very physical and defensive Panama side, Gareth Southgate's side were so ruthlessly efficient that the match was over as a contest long before half time.
Here are four of the most important lessons we learned from England's win on Sunday.
1. Kieran Trippier's Set Piece Deliveries Are Crucial to England's Chances of Success
The statistics say it all. Five of England's eight goals in their first two matches of this year's World Cup have come - in one way or another - from set pieces taken by Kieran Trippier.
Seeing as England often struggle to create clear scoring opportunities in open play, Trippier's dead ball deliveries may represent the Three Lions' best chance of advancing to the latter stages in Russia. His corners and free kicks have generally been excellent so far.
If he can maintain his current level of dead ball consistency, he'll surely be an England regular for years to come.
2. Harry Kane Is Definitely a World Class Striker & England Can't Afford to Lose Him
If there were any lingering doubts about Harry Kane's class, they've been put to bed by his staggering record of five goals in two matches in Russia.
Yes, two of those were penalties, two were close range finishes, and the other one was exceptionally lucky. Nevertheless, those penalties were struck with nerveless aplomb, and Kane was in the right place at the right time for the other three - qualities which mark him out as a great goalscorer.
England really can't afford to lose him if they want to have even an outside chance of winning this year's World Cup.
3. It May Be Time for Gareth Southgate to Drop Raheem Sterling
It's just not happening for the Manchester City star at international level. Admittedly, Sterling played an important role in two of England's goals, but he really should have scored one himself from close range. Apart from a few bright moments, he endured yet another frustrating game for England.
With progress to the round of 16 now confirmed, the clash with Belgium arguably gives Southgate an ideal opportunity to rest Sterling and experiment with a different partner for Kane. One obvious possibility is Marcus Rashford, who performed so impressively against Costa Rica in the Three Lions' final warm-up match.
4. Mexico Are Currently the Only Good CONCACAF Side
Spare a thought for the United States. For a side of Panama's calibre to qualify ahead of them for this year's World Cup, the Stars and Stripes must be in a pretty desperate state.
Panama now have an even worse goal difference than Saudi Arabia. The Saudis at least made a decent fist of their second match against Uruguay, whereas the Panamanians have gone from bad to worse since their solid first half against Belgium.
With Costa Rica also out after two successive defeats, Mexico are the only CONCACAF side to have given an impressive account of themselves in Russia.
