It has finally happened. As the world watched on, and with a strict set of hygiene rules in place, the German Bundesliga became the first major European league to get back under way. And while plenty of aspects were different from before, it would be no exaggeration to call it an historic matchday – not least due to a change in the rules. FIFA.com looks at 10 things that we noticed over the weekend.

Of course it was totally different – but once we got into it, it was much like it always had been. Erling Haaland – who else?– scored the first goal after the re-start, and the image of the celebrations, with the Borussia Dortmund players maintaining their distance from one another in front of empty rows of seats in their imposing stadium, could well become iconic.

The Bundesliga has always attracted interest from abroad, but never to the extent that it enjoyed last weekend. Zlatan Ibrahimovic featured it on his Instagram story ("They said they would do it and they did. Thank you."), while Kylian Mbappe posted on Twitter that he had enjoyed the Ruhr derby. Plenty of broadcasters set new viewing records.

While most people would surely prefer the stadiums to be packed to the rafters, the atmosphere in the empty arenas did create a few talking points. It was easy to hear what the coaches were shouting out (with a number of them saying beforehand that they would have to be a little more circumspect as everyone would be able to share in the message that they were trying to get across), and the same went for what the players were saying to one another, giving us an insight that we had never before been privy to.

From interviews carried out from a distance to substitutes warming up with masks, sitting metres apart from one another or even, as was the case in Leipzig, using an airport gangway to get into the stands, not to mention the creative ways of filling the empty rows of seats, there were plenty of unusual images on display.

A short time ago, The International Football Association Board (IFAB) adopted a change in the laws to allow five substitutes to be used, with the Bundesliga taking on board this modification. On the first matchday after the restart, eight teams made use of the full five. Schalke were the first, with Timo Becker coming on in the 87th minute as his team’s fifth substitute, while Hertha Berlin, Paderborn, Borussia Monchengladbach, Eintracht Frankfurt, Koln, Mainz and Union Berlin all went on to follow suit.

Getting back to league action after such a long break and with no friendlies beforehand was unusual to say the least. And to begin with a number of matches, it was clear that the two teams were feeling each other out, but by the end, there was plenty of high-quality football on display despite the lack of atmosphere. The BVB – Schalke derby, Freiburg’s clever tactics in Leipzig, Gladbach’s lightning start in Frankfurt and the ding-dong battle between Koln and Mainz were just some of the stand-outs of the weekend.

The fans may have been physically absent, but as they watched on via their TV screens, they were very much a presence in the minds of the players. BVB celebrated their derby victory in front of the South Stand which is usually home to the "Yellow Wall", while Gladbach’s Marcus Thuram stayed true to his tradition of celebrating with the corner flag.

"We made a damn good job of it, and by we, I mean Koln and Mainz. We served up a really good football match." Mainz coach Achim Beierlorzer

"Obviously matches without fans seem to go by a little more slowly, so the wait for the final whistle felt a bit longer than normal." Bayern Munchen goalkeeper Manuel Neuer

"Come on, it’s not a friendly!" Heard from one of the Frankfurt staff after his team went 2-0 down to Gladbach in the seventh minute

"Football is football and you just go out and try to enjoy it." BVB midfielder Julian Brandt

"We discussed it beforehand and we knew that it was the same kind of game that we used to play as kids, no more, no less. No fans, just go out there and have fun." BVB goalkeeper Roman Burki

Even prior to the COVID-19 crisis, matches behind closed doors were known in Germany by the rather romantic name of Geisterspiele or "ghost matches". At Frankfurt, they decided that this was a good excuse to play the "Ghostbusters" theme before their match with Borussia Monchengladbach. The visitors proved that they weren’t afraid of no ghosts, however, finding the back of the net twice in the first seven minutes.
