Jakob Silfverberg got a call from Rome shortly after he learned he had become a member of the Anaheim Ducks as part of the trade that saw the Ottawa Senators acquire Bobby Ryan. It came from All-Star defenseman and now-former teammate Erik Karlsson, who himself was just coming to terms with the news.

"He was obviously very shocked at the moment, and so was I," said Karlsson, who was celebrating his anniversary with his wife in Italy when he learned his fellow Swede had been traded. "I didn't expect that on my vacation."

Neither did Silfverberg, who made a solid impression in his first NHL season with Ottawa, contributing 10 goals and nine assists while playing all 48 games.

"I didn't see it coming at all," Silfverberg said Friday prior to his first game back at Canadian Tire Centre. "Of course, if you get traded you start wondering why you got traded and that kind of stuff. But looking back to my previous season I think I played well and I can't say I'm disappointed in myself or anything like that. I'm happy where I am right now."

Karlsson, who won the Norris Trophy in 2011-12, was surprised the 23-year-old right wing's tenure with the Senators proved to be so brief.

"He's under development and I think he's someone that I thought was going to be here for quite some time. But these things happen," Karlsson said. "We had to give something good up to get something good and unfortunately he was part of that trade. Anaheim probably recognized that he was going to be a pretty good player."

In addition to Silfverberg, Ducks general manager Bob Murray obtained right wing Stefan Noesen, who was chosen No. 21 by Ottawa in the first round of the 2011 NHL Draft, as well as the Senators' first-round pick in 2014.

Silfverberg was the element that sealed the deal for Anaheim and his early play has paid dividends for the Ducks.

He has seven points in 10 games, including four goals in his first four games.
