Henrikh Mkhitaryan and Pierre-Emerick Aubameyang have been at the club for a short while, but can already be considered two of Arsene Wenger’s most significant signings.

It’s far too early to call Mkhitaryan or Aubameyang a success, but their arrivals have excited the fans like few other signings.

Arsene Wenger has brought in many great players, several of which weren’t well known before they arrived.

The likes of Thierry Henry, Patrick Vieira and Freddie Ljungberg were far from household names until they played for Arsenal.

Similarly, young talents such as Cesc Fabregas, Aaron Ramsey and Robin van Persie practically grew up with the club and served it with distinction.

Mkhitaryan and Aubameyang, though, are well-known, ready made talents.

Fans know what they’re all about and what they can bring to the team.

Signing them is an accomplishment for the club, much in the same way that Mesut Ozil’s and Alexis Sanchez’s arrivals were.

Putting them into the list of Wenger’s best signings already may seem hasty, given they’ve only been with us a short while.

It’s on significance alone that they make the list, albeit at the bottom.

They can’t be ranked above many of the legends that Wenger brought in to the club due to sheer scale of their accomplishments, both as a team and as individuals.

Nor can they be any higher than many of the players who played during the Emirates Stadium era, simply because they’ve played less.

So, here is my list of Wenger’s top twenty signings, including Mkhitaryan and Aubameyang:
