Unai Emery is officially the new Arsenal manager.The Gunners announced on Wednesday morning that the 46-year-old will replace Arsene Wenger at the Emirates Stadium following a late decision to snub Mikel Arteta.Emery arrives off the back of a two-year stint at Paris Saint-Germain in which he won several domestic competitions but was never able to make an impact in the Champions League.The Spaniard expressed his excitement at the task of making Arsenal competitive once again.“I am thrilled to be joining one of the great clubs in the game," Emery told the club’s website."Arsenal is known and loved throughout the world for its style of play, its commitment to young players, the fantastic stadium, the way the club is run.“I’m excited about what we can do together and I look forward to giving everyone who loves Arsenal some special moments and memories."

Emery is on Twitter

Immediately after his appointment was announced, Emery changed his profile picture on Twitter to Arsenal’s crest and added: ‘@Arsenal Coach,” to his bio.

Only a few managers use social media and Arsenal supporters are joking that it won’t be long before Emery deletes his accounts.

This is the same fanbase that brought us Claude and DT, the stars of ArsenalFanTV, and frequently called for Wenger’s dismissal using the #WengerOut campaign.

If things go wrong early for Emery, his mentions are bound to be inundated with tweets from angry Arsenal fans.

So it probably won’t be long before Emery decides to close his accounts.

After all, Arsenal fans can be relentless.

For what it’s worth, Emery is a rather frequent tweeter.

He regularly posted motivational messages during the final weeks of PSG’s season and even sent a touching tweet about Wenger when it was announced that the Frenchman would leave Arsenal after 22 years at the club.

“Impossible to talk about @Arsenal, the @premierleague and the profession of coaching without mentioning Arsène Wenger, one of the references probably. Thank you Arsène!,” Emery wrote.

His tweet when Sir Alex Ferguson was rushed to hospital after suffering a brain haemorrhage was also lovely.

“All my thoughts are with Sir Alex Ferguson. I wish you a full and speedy recovery. Stay strong!,” the former Sevilla boss wrote.

Yet, as the aforementioned tweets show, fans don't expect Emery to last much longer on the social media platform.
