Once you hear it, you can't unhear it.
While most of the coverage of January's longest-running transfer saga focused on Alexis Sanchez's arrival at Manchester United, Arsenal have undeniably got themselves a brilliantly talented player in return in the form of Henrikh Mkhitaryan.
Mkhitaryan will hope to revive his career at the Emirates after falling out of favour with now-former manager Jose Mourinho.
"I'm very happy that we could finish this deal and I'm very happy to be here," Mkhitaryan said. "It's a dream come true because I've always dreamed of playing for Arsenal.

"Now that I'm here, I'll do my best for this club to create history."
The swap was expected since last week and it was reported that Mkhitaryan was the one delaying confirmation of the move.
But it's done now and the Armenia international spent his Monday speaking to Arsenal's official website.
In one video which was posted to welcome Mkhitaryan to the Gunners, supporters reckon they've spotted a message. Fans think that Mkhitaryan can be heard saying: "Pierre, do you want to come out here?"

With Borussia Dortmund's Pierre-Emerick Aubameyang, a former teammate of Mkhitaryan's, linked with a move to Arsenal this January, supporters came to the conclusion that Mkhitaryan was trying to persuade a mate to join him.
