Arsenal fans' biggest fear heading into the summer transfer window was the thought of losing Mesut Ozil or Alexis Sanchez to a European rival.
Following a frustrating spell of selling their best players - Robin van Persie, Cesc Fabregas and Samir Nasri all left within the space of a year - the Gunners are now in a place where they should be holding on to their best players and building around them.
And by and large they've done that since 2012, with top quality signings arriving at the Emirates Stadium and deadwood heading in the opposite direction.

Well, that trend could be about to take a turn for the worse.
Whilst the aforementioned Ozil and Sanchez are the club's biggest names, Arsenal possess another highly sought-after star: Hector Bellerin.

The Spain international, who arrived in north London from Barcelona's La Masia academy in 2011, has been a subject of interest across Europe since bursting onto the scene against Borussia Dortmund in the Champions League two years ago.
Since then, Bellerin has become one of the Premier League's best and most consistent right-backs.
It seems only fitting, then, that former Barcelona manager Pep Guardiola is interested in bringing him to Manchester City - and it would seem his young compatriot is also keen.
According to Spanish outlet Mundo Deportivo, Bellerin is contemplating a potential move to the Etihad.
Now, it's worth taking such speculation with a pinch of salt considering how the 21-year-old has previously expressed his happiness at the Emirates Stadium, but Arsenal have a chequered history when it comes to City.
Indeed, in 2011, both Nasri and Gael Clichy completed controversial moves up north, with Bacary Sagna joining them three years later.
Furthermore, Guardiola is famed for his effectiveness in nurturing talented full-backs, with Dani Alves and Jordi Alba thriving under his tutelage at the Camp Nou.
The thought of playing under the Spaniard will undoubtedly be a tempting one for Bellerin, with a representative of his reportedly telling Mundo: "He is happy at Arsenal... but the option of City exists, it pleases him and what's more, Pep [Guardiola] is there."
What was meant to be an exciting summer for Arsenal could soon become a frustrating one.
Not only does Arsene Wenger face a battle to keep the club's brightest prospect, but his ongoing bid to sign a world-class striker continues to suffer setbacks.
Alvaro Morata, Alexandre Lacazette, Romelu Lukaku and Gonzalo Higuain have all been linked with the Gunners in recent weeks yet, for one reason or another, potential moves keep being ruled out.
Ultimately, if Arsenal want to sign the calibre of striker their fans desire, they must shell out at least £50 million.
