Five things we learned: Serbia 1-2 Switzerland
Serbia are exciting, VAR doesn't work all the time, Shaqiri still the talisman: five things we learned as Switzerland produce a comeback win over Serbia.
SERBIA ONE OF THE MORE EXCITING ATTACKING SIDES
After the first round of matches there were plenty of sides on show who were functional, rather than fantastic, when looking to attack.
Serbia showed in Kaliningrad that they have plenty of options in their game; they might have scored off a set piece but they created plenty thereafter from open play.
Offensive full-backs, powerful driving runs from midfield and the ever-present threat of Aleksandar Mitrovic at centre-forward made them an exciting side to watch - and the prospect of watching them against Brazil next week is an enticing one.
One key point to improve upon: a clinical edge. They could have been out of sight even before Switzerland came back into the match.
EVEN VAR CAN MISS A BLATANT PENALTY
There's no question that the presence of the Video Assistant Referee has led to an increase in penalties at the World Cup.
There wasn't one between Serbia and Switzerland - but there absolutely should have been.
Mitrovic found himself grappled to the floor inside the penalty box during the second half, a blatant foul which the referee or his assistants should have seen. And when they didn't? Surely VAR would have been able to notice on a playback, particularly after Mitrovic's protestations.
Apparently not.
BRAZIL HAVEN'T DONE ENOUGH TO QUALIFY YET
The comeback from Switzerland denied Serbia a place in the last 16, which would have been guaranteed had they themselves won - but it now means that three sides are playing for the two spots on the final day in Group E.
Serbia certainly showed enough to suggest they'll give Brazil a game, but now Switzerland, level with the South Americans on four points, will be favourites to progress.
It could be a straight fight for Serbia: Win and through, anything else and out.
GAVRANOVIC OR EMBOLO MUST START FOR SWITZERLAND
Simply put, there was no threat from the Swiss in the first half, with Haris Seferovic leading the line.
His touch and movement were both poor, he didn't offer enough link play and he was certainly no goal threat from him before he was subbed at the break.
After starting - and being hauled off - in both group games so far, it's time for Switzerland boss Vladimir Petkovic to accept that he must look to other options.
Switzerland were much more fluid in open play and, of course, scored their two goals in the second half once both Mario Gavranovic and Breel Embolo were on the pitch.
SHAQIRI REMAINS SWITZERLAND'S KEY MAN
A quiet opening match, the importance of Blerim Dzemaili and an earlier wonder-goal from Granit Xhaka: it was beginning to look as though Xherdan Shaqiri was well down the list of Switzerland's stars.
That all changed in the second half: a virtuoso display, a key impact on the game...and a tremendous late winning goal.
Even the goal came after Shaqiri had almost added a spectacular second, whipping in a strike onto the crossbar.
He's still the most important piece of the puzzle for the Swiss.
