3 things we learned in the Premier League on Saturday

There were a number of familiar scenes in the Premier League on Saturday, triggering memories of last season from one side of the United Kingdom to the other.

Jamie Vardy and Wes Morgan scored as Leicester City survived a scare from Swansea City, Arsenal claimed its first victory in Arsenal-esque fashion, and Marcus Rashford scored in "Fergie Time" as Manchester United defeated Hull City in a fascinating, but cruel fixture.

Here's what we learned in the Premier League on Saturday:

Vardy can still outpace defenders like it's nothing

Vardy wasn't about to let a third match go by without getting his name on the scoreboard.

Having failed to find the back of the net in Leicester's first two games, Vardy silenced the critics in the Foxes' 2-1 victory over Swansea. Not only did the cast-wearing forward score his first goal of the campaign, but in the pouring rain he exhibited all the qualities that made him so lethal in last year's Premier League conquest.

Vardy's goal was as classic as Vardy's goals come. Upon receiving an aerial pass from Danny Drinkwater, the 29-year-old casually outpaced Jordi Amat before rocketing the ball past Lukasz Fabianski.

But it wasn't just the goal. Vardy troubled Swansea's back line from kick-off until the final whistle, constantly wreaking havoc in the Swans' penalty area and making life miserable for defenders. It was his best performance of the season, and Leicester's supporters will obviously be hoping for displays of that calibre in the coming months.

Arsenal's supporters don't need to panic

Entering Saturday, many of Arsenal's supporters were on the verge of a heart attack, while anything less than three points at Watford would have taken their already-high blood pressure to another level. Luckily for those who bleed red, the Gunners produced a wonderful performance, and then some.

Using a classic mix of approach play and clinical finishing, Arsenal outclassed Watford, particularly in the first half as all three of the Gunners' goals were tallied before the interval. It was an illuminating display from Arsene Wenger's side, and it came on the heels of two performances that manufactured angry episodes of ArsenalFanTV.

Mesut Ozil was again at the heart of some fine football, Alexis Sanchez was phenomenal, and even if just for 90 minutes, Arsenal's lack of activity in the summer transfer window was forgotten.

There's no need for Arsenal to hit the red button just yet.

Rashford is football's coolest teenager

Listen up, Jose Mourinho - Rashford is more than good enough for England's senior team.

After Mourinho welcomed the controversial decision to drop Rashford from England's squad, the teenager responded with gusto, scoring in the 92nd minute to give United a 1-0 victory at Hull, bringing an abrupt end to the Tigers' undefeated start.

As was the case when injuries forced Louis van Gaal to hand Rashford his professional debut, the 18-year-old was in the right place at the right time. He knew exactly where to be as Wayne Rooney cut into Hull's penalty area, once again displaying maturity beyond his years. However, Rashford did remind the world of his adolescence by celebrating with the Red Devils' supporters, some of which may have been injured during the festivities.

Not only did Rashford let Mike Phelan know what it feels like to score in "Fergie Time," but he also achieved a surprising milestone, considering Mourinho once proclaimed to have "promoted 49 youth players from academies."
