Arsenal and Leicester City have gotten rather acquainted with each other in the past few months.
The biggest transfer story pre-Euro 2016 was the Gunners' pursuit of Jamie Vardy, which ended with the Leicester forward committing his future to the Foxes by signing a four-year contract extension.
Like the resilient buyer at a car boot sale, Arsenal came back, undeterred in their approach to weaken the Premier League champions.

Arsene Wenger quickly turned his attentions to Riyad Mahrez, who won the PFA Player of the Year award for last season's heroics.
Having managed to convince Vardy to stay at the King Power Stadium, the hope is that Claudio Ranieri can work his magic with the Algerian winger.
There is, of course, the chance that Mahrez follows the path taken by N'Golo Kante by joining a perennial top-four club. It would be a shame for Leicester to lose two of last year's best players but that's the problem the Foxes, who aren't considered among England's big boys, face.
Vichai Srivaddhanaprabha's message to Arsenal
Everyone from Ranieri to Lee Chapman, Vardy's lookalike who has shot to fame, is desperate to see Mahrez remain a part of Leicester's incredible journey. And owner Vichai Srivaddhanaprabha has given them reason to hope with his latest Instagram post.
The billionaire businessman took to social media to publish a photo of himself with the 25-year-old, his fingers clasped to Mahrez's ear.
The caption is a joke Srivaddhanaprabha shares about the pair's conversation: "VS: You Not for sale!! Mahrez: Ok boss."
August 31 deadline
Mahrez has reportedly been given an improved £100,000-a-week contract by Leicester to convince him to stay but, until he's pictured putting pen to payer, Srivaddhanaprabha's words aren't to be taken literally.
The Foxes have done well to enter August without too many reports of a bid emerging but, as we've seen with the swiftness of Georginio Wijnaldum's move to Liverpool, transfers can be completed in a matter of days. And Arsenal have until the 31st before the deadline.
Leicester must pray that Arsenal complete their moves for Julian Draxler or Alexandre Lacazette. According to the Independent, Wenger has been given permission to splash the cash on bringing the Lyon striker to the Emirates, while Draxler is keen to leave Wolfsburg.
