Arsenal chief executive Ivan Gazidis has indicated there are more big signings to follow after the club confirmed the arrival of Alexis Sanchez from Barcelona.

The Gunners completed their stunning £30m deal for the Chile international on Thursday in a move that is expected to spark a series of further arrivals at the Emirates Stadium.

France full back Mathieu Debuchy is expected to join Sanchez in the coming days having reportedly completed his medical with the club ahead of an £11m switch from Newcastle United.

The club are also expected to add a holding midfielder to their ranks with World Cup finalist Sami Khedira, Southampton's Morgan Schneiderlin and Lars Bender of Bayer Leverkusen among the clutch of names being considered by the club.

Having seen rivals Chelsea, Liverpool and Manchester United all make significant additions to their squad already, Arsenal fans are eager to see their club follow suit and the club's chief executive has reassured them there is more to come.

"It's a great signing, were really happy about it," Gazidis told Arsenal FanTV following the launch of the club's new kit ahead of the 2014/15 campaign. "I'm happy for the club but we've got more work to do."

Sanchez, 25, becomes the club's second high profile arrival in as many years following the deadline day signing of Mesut Ozil last summer.

Upon his arrival at the club he said: "I'm so happy to be joining Arsenal, a club which has a great manager, a fantastic squad of players, huge support around the world and a great stadium in London," Sanchez told the club's official website.

"I'm looking forward to meeting my new team-mates and to be playing for Arsenal in the Premier League and Champions League. I will give my best to Arsenal and want to make all the supporters happy."
