European champions Chelsea opened their tour of the United States on Wednesday with a 4-2 win over the Seattle Sounders as striker Romelu Lukaku led the way with two first half goals.
The Belgian slotted home in the third and 45th minutes while newcomers Marko Marin and Eden Hazard also scored for the Blues.
"I feel the pressure, but you play for Chelsea, there's pressure and we won, so that's the most important thing," Lukaku said. "The goals were good for me, but the most important thing is the team. I enjoyed it a lot."
It was the first match for Chelsea since they beat Bayern Munich two months ago to win their first UEFA Champions League and add to their FA Cup win.
Fredy Montero scored twice in the first half for the Sounders but they were unable to muster enough attack in the second half in front of a crowd of 53,309 at Century Field.
However, they managed to keep the score closer, unlike last year when they were routed 7-0 by Manchester United.
"We were looking to (have) a good workout, good possession, some good combination play and slowly integrate new players and also see some of our younger talents that we have in the club that will hopefully be the future of the club," said Chelsea manager Roberto Di Matteo.
Chelsea were without five of their biggest names for the first stop on their four-game pre-season American tour.
The trip also features the first football match at the new Yankee Stadium, against Paris Saint-Germain on Sunday, before the West London side face the Major League Soccer all-stars in Philadelphia and Italian giants AC Milan in Miami.
Spanish star Fernando Torres - who helped Spain to win UEFA EURO 2012 this month - will join the tour later, as will Portugal's Raul Meireles, French midfielder Flourent Malouda and England defenders Ashley Cole and John Terry.
