Sheffield United were given a stern warning after just 75 seconds as Saka struck the post and Jack Robinson had to clear the rebound off the line from Martinelli’s close-range strike.
Three minutes later, the Blades were not let off so easily. Jorginho fed Rice on the left byline and he cut the ball back to Odegaard, who had an easy finish into an empty net.
The Gunners had their second soon enough as Saka burst past Auston Trusty far too easily down the right and his low cross was put into his net by a clumsy Bogle.
Arsenal made it three almost instantly as Rice won the ball high up and feed Jakub Kiwior on the overlap. The Polish defender pulled the ball back to Martinelli whose deflected shot flew in.
Arsenal’s left-hand side continue to fire as they made it four. Martinelli picked Ahemdhodzic’s pocket deep in the Blades half and fed Havertz in the box, who had a simple finish into the far corner.
And then Saka returned down the right for No 5 as he jinked past substitute Osborn to find an unmarked Rice in the box, who swept home with ease.
That was Saka’s last action of the game as he was taken off at half-time for the returning Vieira – as the Gunners continued their ventures forward.
Arsenal’s sixth fell to White as the defender picked up Havertz’s nice take-down and pass in the box to rifle home with his left foot.
Arsenal manager Mikel Arteta to Sky Sports:
“I love the way the team played, the quality that we showed, the aggression we showed with and without the ball. We were really determined from the beginning, we were all worried as it’s a tricky game against a tricky team who had played well against some big teams.
“We have to continue what we are doing, I’m really happy with how we played, really happy to get players back after a long time like Fabio and Thomas. On Saturday is Brentford, we enjoy it today then tomorrow is Brentford, Brentford and Brentford.
“It’s going to be crucial if we win the remaining games. In order to do that, we have to beat Brentford and that’s the most important thing now.
“We really love our players and our job is to improve them and to give them the resources and to put them in situations where they can explore their qualities. The fact so many are scoring creates confidence and threat around the team that anyone can score a goal.
“I know how tough it is going to be against Brentford. It always is. We are trying to prepare the game in the best possible way. Performing the way we are doing, and earning the right to win the game.
Arteta explains Arsenal Dubai trip
On what happened in the mid-season trip to Dubai: “We had a really condensed period and we had lot of players out. We had a few defeats without deserving them. It was a good wake-up call. It was about putting things aside, being together, enjoying nature is a positive thing to do.
On Saka and Martinelli’s withdrawals after half-time: “Bukayo was feeling sick and wasn’t feeling right so we decided to take him off. Gabby is just a cut, it’s a slight cut and we have to see how it is.”
