There were a great many positives for Sweden fans to take away from the performance in Monterrey in the small hours, but still, one or two question marks remain. Here, Flashscore takes a look into the main takeaways from Sweden 5-1 Tunisia.
Delivering when it matters most
With three points and a positive goal difference likely to be enough needed to qualify for the Round of 32, Sweden have given themselves a great chance of progressing. Just as in the playoffs in March, they delivered when the pressure was on.
As has already been stated countless times, Blagult failed to win any of their six qualifiers but had the playoffs to fall back on thanks to their UEFA Nations League (UNL) performance. They also failed to win either of their World Cup warm-up matches, losing heavily to Norway and conceding a late equaliser against Greece.
But for the third time under Potter, Sweden have come up with the goods when it mattered most. The playoff matches against Ukraine and Poland were certainly "must win" games, and with the highly-fancied Netherlands and Japan to come in Group F, the Tunisia fixture was as good as a must-win game for the Swedes, too.
Those three, in which Sweden scored 11 times, are the only wins under Potter so far, suggesting this side are one for the big occasion, and that the confidence and belief in the camp is in a good place, having been at arguably an all-time low back in the autumn.
An attacking pair, or two individual strikers?
A goal apiece for the elite striking duo of Alexander Isak and Viktor Gyokeres vindicated Potter's decision to start both up front, despite Sweden playing their best football under him in March when Gyokeres was the lone striker in the playoffs.
The pair even assisted each other for their goals - Gyokeres sent Isak on his way down the left before the Liverpool man cut in and fired across the goalkeeper, then, Isak's pressure won the ball high up the pitch and Gyokeres did the rest.
Despite that, the two often seemed to be playing their individual games, rather than working in tandem. From the opening minutes, when Gyokeres shot wide after electing to go alone, both players often looked more dangerous when playing more selfishly.
The Arsenal man may have picked up an assist, but Isak's goal was still an individual effort, while a ricochet off Isak took the ball into Gyokeres' path for his goal - had Isak maintained control, he may have taken the chance on himself.
But, if that individuality is the best form of teamwork, Sweden fans won't mind one bit, and that unpredictability may serve them well with tougher tests ahead.
Not all about the big two up top
Goals from Isak and Gyokeres were the key to Sweden's small chance of success according to the vast majority of pundits and experts before kick-off, but both were outshone by Yasin Ayari, who scored the first and last goals in the rout, both from outside the area.
The fourth Swedish goal of the game was scored with the first touch of the game by Matthias Svanberg, just 18 seconds after coming on as a second-half substitute - the second-fastest goal by a replacement in World Cup history.
With those three strikes, Sweden have proven they are not reliant only on the front two for goals, they have strength coming off the bench and Potter knows how to utilise his substitutes to make an instant impact. Following criticism of some of his selections when the squad was announced, Potter has again responded.
Who needs qualifiers?
A lot was made of Tunisia's defence in qualifying, where they didn't concede a single goal in 10 matches as they cruised through to another major tournament. Paraguay conceded only 10 in 18 matches in the tough CONMEBOL qualifying section. They have conceded a combined nine goals in their openers.
Brazil, on the other hand, suffered their worst qualification campaign to date en route to North America, but a similarly bad performance in qualifying for the 2002 World Cup preceded one of the most dominant World Cup wins of all time. Unsurprisingly, Brazil fans are using that as a positive omen.
The point being, whether good, bad or indifferent, teams' records in qualifying are rarely a good indicator of how they will do once the tournament kicks off. As last night proved, using Sweden's qualifying record as a stick to beat them is both pointless and ineffective.
All that matters when tournaments are concerned is that you qualify, by hook, crook, or playoffs in Poland. In the space of 90 minutes, Sweden have gone from a team who lost to Kosovo twice, to a free-scoring side who can cause any side problems.
Still no clean sheets
Omar Rekik's goal to make it 2-1 just before half-time meant that Sweden still haven't kept a clean sheet since a 2-0 friendly win away in Hungary on 6th June last year - a run of 12 matches.
In terms of competitive football, the last time Sweden kept the opposition out for 90 minutes was a 6-0 win over Azerbaijan in the final game of the UNL campaign in November 2024 - 10 meaningful games ago.
Offence sells tickets, defence wins championships - the old saying rings true here. Sweden cannot go deep into this tournament by letting in soft goals like the one they conceded last night, and while attack may be their best form of defence, better sides than Tunisia will do more to limit them going forward as the tournament goes on.
There was nothing goalkeeper Kristoffer Nordfeldt could do about Rekik's header, and the AIK stopper held firm otherwise to prevent The Eagles of Carthage from getting back into the contest, but still, he needs more support from those in front.
