ARGENTINA international Jonas Gutierrez has become Newcastle United's first signing of the summer.

The right-sided attacker joins the Magpies from Spanish outfit RCD Mallorca on a five-year deal for an undisclosed fee.

Gutierrez has the nickname "Spiderman" for wearing the superhero's webbed mask during flamboyant goal celebrations.

And the move to St. James' Park comes as a perfect birthday present for the wide player, who turns 25 on Saturday.

Jonas said: "I cannot tell you how excited I am to be joining Newcastle United.

"The Premier League is a great place to play and I cannot wait to meet my new team-mates and prove myself to the Newcastle United fans."

United boss Kevin Keegan added: "Jonas is a wonderful signing for us.

"I know a lot of other clubs have been interested in him. He'll be a terrific addition to the squad.

"He's an exciting player and I'm sure our fans will enjoy watching him."

Jonas began his career with Velez Sarsfield in his native Argentina, helping the club win the Primera Division title in 2005 before moving to Spain.

He won his first cap against France in February 2007. Most recently, he played for his country on June 18 in a 0-0 World Cup qualifying draw away to Brazil in Belo Horizonte.

As a result, Jonas will now have a break before linking up with his new colleagues for pre-season training later this month.

United fans will be able to see Jonas in action in the pre-season friendlies against PSV Eindhoven (August 6) and Valencia (August 9) at St. James' Park.
