BRAD Smith described as "an amazing feeling" lifting the MLS Cup with Seattle Sounders.

The Cherries loanee started the contest against Toronto in front of a record sold-out crowd of 69,274 at CenturyLink Field.

Kevin Leerdam put Sounders ahead before Smith was replaced on 61 minutes, with Victor Rodriguez and Raul Ruidiaz sealing victory before Jozy Altidore made it 3-1 at the death.

Speaking after helping Seattle clinch the second MLS Cup in their history after also winning in 2016, Smith, who is the first Aussie to win the trophy, told the Sounders website: "From the moment I set foot in Seattle, when I met with the manager and the coaching staff, it was an easy decision (to join).

"This is what this city deserves. For me personally it's an amazing feeling.

"We didn't start the game as well as we wanted. We were quite erratic at times.

"But once we came in at half-time we calmed down really and realised it was just another game. Once the goals started going in and we got the win, to do it for these fans is incredible.

"You see what it means to everyone involved in this city and this club."

He added: "I was nervous. I think a few of the other guys were the same.

"But we went out there, it wasn't pretty but at the end of the day all you have to do is win these games. That's what we did and it's an amazing feeling for everyone involved.

"I could tell from when I first arrived it was such a special group. I said we were going to do special things."

Smith became the first Australian player to win the MLS Cup, with five others failing to lift the trophy in their time in America, including former Everton star Tim Cahill.

Smith is set to miss Sounders' trophy parade through the city of Seattle tomorrow as he flies to join up with Australia for international duty.

He said: "I've got to go to the national team so I'll be celebrating on my own.

"I'll meet up with a few of the guys in the off-season so I'll celebrate with them then."
