Arsenal unveiled their first signing in the summer transfer window on Thursday -- Chilean Alexis Sanchez from Barcelona.

Sanchez transfer saga has been going on throughout the World Cup in Brazil. The Gunners have beaten off competition from Premier League rivals Liverpool and Italian giants Juventus to land the highly rated forward.

The move has garnered a lot of interest, as well as a lot of reactions from the current and former players. Arsenal players Mesut Ozil and Theo Walcott have shared their joy at the signing and sent their messages welcoming Sanchez to Arsenal.

Even former Gunners legends Thierry Henry and Ray Parlour have welcomed Sanchez to Arsenal, saying they look forward to seeing the Chilean in action.
