Arsenal has announced the signing of former Chelsea winger Willian on a three-year deal. Arsenal made this known via its Twitter handle on Friday. The 32-year-old left Stamford Bridge at the end of his contract after seven years at the club, with Chelsea only willing to offer him a two-year deal rather than the player’s desired three years. Arsenal moved into pole position to sign the Brazil international by offering a three-year contract last week.
