Ramsey netted the first after just five minutes when he reacted swiftly to Asmir Begovic's save from Ozil's free kick. The Welshman prodded home his eighth goal in 10 games and his fourth in the last three.
From there the Gunners looked very comfortable as they stroked the ball around with ease. To their credit, the ever-improving Potters ground their way back into the game and deservedly equalized after Geoff Cameron slotted past Wojciech Szczesny from fully 18 yards.
Perhaps against type, the Gunners then took the lead from a corner as Mertesacker climbed highest to reach a dangerous Ozil corner to flick the ball into the back of the net. The irony of Arsenal scoring a Stoke-style goal was not lost on their fans as they roared with approval.
Sagna's late goal, from Ozil's third assist of the day, finished the game as a contest, but it came against the run of play with Mark Hughes' team well on top.
The Gunners may have won 3-1, but this was far from a comfortable victory.
