Viktor Gyokeres scored his first two Arsenal goals as the Gunners gave Leeds a harsh lesson in the step-up to the Premier League with a 5-0 win at the Emirates. However, victory came at a cost for Mikel Arteta as Bukayo Saka and Martin Odegaard hobbled off injured just eight days before Arsenal's trip to Liverpool. Arsenal edged ahead of north London rivals Tottenham at the top of the table on goal difference, as the only two sides so far with a 100 percent record from their opening two games. Arteta has been backed to the tune of £260 million ($350 million) on seven new signings in a bid to deliver the club's first Premier League title since 2004 after finishing second for the past three years. 

Arsenal's latest £60 million recruit Eberechi Eze was paraded before kick-off to a huge ovation after turning his back on a move to Spurs to return to his boyhood club. Gyokeres also showed why he was signed from Sporting Lisbon as the solution to Arsenal's need for a killer number nine. But Arteta said the injuries to Saka and Odegaard, just days after Kai Havertz was also ruled out by a knee injury, showed why he needs such a deep squad. "We've learned the lesson from last season and the squad that you need right now," said Arteta. "That is why we acted in the market the way that we have done because you have so many games, anything can happen. "It happened to two of our most important players -- we already lost Kai -- so we are going to need everybody at his best and a lot of luck as well to not lose others."

Arsenal had to rely on their threat from set-pieces to grind out a 1-0 win at Manchester United on the opening weekend of the season. Despite a dominant start to the game, that was how the the Leeds defence was prised open. Timber had scored just twice in 52 Arsenal appearances before Saturday. The Dutch international doubled that tally as he firstly got his head to Rice's inviting delivery on 34 minutes. Odegaard then made his departure after appearing to injure his shoulder falling heavily to the turf. Saka soon had the Emirates crowd back on their feet when he drilled Timber's pass high past Lucas Perri with his supposedly weaker right foot. Gyokeres had at one point been a target for Leeds during his days with Coventry in the Championship before making the move to Portugal. The Swede's ability to succeed in the Premier League has been questioned despite his prolific record of 97 goals in 102 games for Sporting.
