What a difference a week can make in the weird world of Arsenal fandom. Last Saturday, many were just about ready to pack up and go home after an uninspiring 0-0 draw against Leicester City.
One point from their opening two games meant the prospect of another season scrapping for the top four was looming large. Worse yet, Arsene Wenger seemed reluctant to make another significant signing despite a clear need for reinforcements.
But the sun is shining in north London once again, at least, that is, unless you are a Watford fan. Arsenal reaped more misery on Walter Materazzi's men by scoring three first-half goals at Vicarage Road.
Santi Cazorla, Alexis Sanchez and Mesut Ozil all found the back of the net before new Watford signing Roberto Pereyra added a consolation in the second half.
After the final whistle, Wenger confirmed deals for Shkodran Mustafi and Lucas Perez were just a few bits of paperwork away from being completed. What a weekend.
Here are five things we learned:
Rob Holding is a genuine prospect
Eyebrows were raised when Arsenal paid a paltry £2million to sign the 20-year-old centre-back from Bolton Wanderers. Had he been a real prospect, surely he would have cost multitude times more. Fans also wondered why no other Premier League clubs were in for him.
Wenger hit the nail on the head when he apologised that Holding came so cheap and it is clear that cost has no bearing on ability. Holding started his third straight Premier League game and was once again commanding alongside Laurent Koscielny.
Take a look at his statistics:
Granit Xhaka is worth £35m
£35m for a defensive midfielder with no Premier League experience seemed a high price to pay. Granit Xhaka became one of Arsenal's most expensive players ever when he joined from Borussia Monchengladbach earlier this summer and fans were expecting a lot from him.
Today, against Watford, was just his second start in English football but he already looked very much at home. The reaction on Twitter appeared to suggest the Swiss had a case for being named the man of the match.
Alexis Sanchez is an option up front
Alexis Sanchez was ineffective against both Liverpool and Arsenal and fans were worried when, once again, he was named as the lone striker against Watford. But the Chilean took advantage of the weaker opposition and the service of Mesut Ozil to put in a brilliant display.
He won the penalty, scored the second goal and directly assisted the third. Lucas Perez may be about to arrive from Real Sociedad but he's got a job getting into the team.
Hector Bellerin is simply Barcelona
Arsenal fans are trying to ignore it but Hector Bellerin is fast turning into a right-back worthy of Barcelona's starting XI. Having lost Dani Alves to Juventus, Barca launched a tentative enquiry for the 21-year-old, which was firmly rejected. If he keeps playing like this, it won't be a long time before they return.
The Spaniard was, once again, a huge threat going forward while his defensive game has clearly taken another step up over the summer. He may be happy in a red shirt for now, but the chance to star for his hometown club will eventually present itself.
Arsenal have signed two players
After the match, Wenger confirmed that deals for Valencia's Mustafi and Real Sociedad's Perez were virtually done. They both passed their medicals at London Colney on Friday and only a few bits of admin stand between them and official confirmation.
He told reporters: “They’ve both had medicals but we need to complete the paperwork.”
