When looking at Unai Emery's Arsenal tenure, all sorts of players gave him nightmares, especially at Tottenham.
The Spaniard won just one of four north London derbies he took charge of, failing to keep a single clean sheet during that time as players like Harry Kane often got the better of him.
What happens during the Arteta reign is unclear but one thing that is clear, is that Tottenham could bring a player to north London that gave Emery and his team the runaround earlier this season.
Coincidentally, that also happens to be another former Spurs player, one who was tipped for stardom by Mauricio Pochettino when he was coming through the ranks.
Now playing abroad, he could walk through the door for a fee over £20m.
Reports from Desportivo de Guimarães (via Sport Witness) claimed this week that Marcus Edwards could be set for a phenomenal return to Spurs. However, they will have to fight off interest from Manchester United too.
Edwards, it would appear, is a wanted man and could cost somewhere in the region of €20m-€25m (£18.1m-£22.6m).
Neither side are yet to begin negotiations but Vitoria, his current team, are under no obligation to sell given he doesn't have a release clause.
GIVEMESPORT'S Matt Dawson says...
This would be quite the reunion for Edwards and Spurs. Although Tottenham don't necessarily need a winger in the market, primarily because of Steven Bergwijn's arrival, it's hard to ignore the talent he possesses.
Pochettino once compared him to the great Lionel Messi, tipping the 21-year-old to reach the very top of the game. However, he departed under the Argentine without making a very big dent on the first-team picture.
Though, since playing in Portugal, he's made tremendous strides. The Englishman has scored seven goals in all competitions, even netting against Arsenal in the Europa League.
Although the Gunners eventually prevailed 3-2, he was a constant thorn in the defence, causing Kieran Tierney all sorts of problems.
Edwards attempted four dribbles, completing 50% off them, while he also completed a key pass and scored from his only shot in the match.
It was a brilliant performance that very nearly caused an upset at the Emirates Stadium.
That display proved he has what it takes on one of the biggest stages in the Premier League and perhaps it was something that caused his former employers to stand up and take note.
It'll be interesting to see whether Jose Mourinho and Daniel Levy launch a bid in the coming weeks or months.
