Captain Alastair Cook has praised a "very special" performance after England defeated Sri Lanka by 110 runs in the first one-day international.
Cook, 26, was captaining the England one-day side for the first time on home soil, and was extremely happy with the rain-affected win at The Oval.
"The way we batted and handled the rain break was very special," Cook said.
"It's a really good start [as captain], but let's not get too carried away about how I did or the team did."
Cook added: "It's just a good start and we have to keep our feet on the floor. We're not in it for personal plaudits, we're in it to win games of cricket."
England had made 229 for eight in a match reduced to 32 overs per side because of a three-hour rain delay.
Bowler James Anderson was man of the match with figures of 4-18, while Craig Kieswetter top-scored with 61.
And as Sri Lanka were bowled out for only 121, Cook felt Anderson was particularly important in England's victory.
"It doesn't get much better than that," he said.
"I thought it was an outstanding performance from all our bowlers but Jimmy up front...to get them 15 for four and get their danger men out got us ahead of the game."
After struggling at the 2011 World Cup, Anderson was happy just to be included in the squad, but feels there is more to come from himself and others.
"We had a frustrating winter in the one-day form of the game and one game's not going to make us a complete unit," Anderson said.
"You've always got a point to prove. We've got a great squad of fast bowlers so you've always got to prove a point.
"We've got a lot of improving to do and hopefully we can continue to do that in the series," he added.
Despite a heavy defeat, Sri Lanka captain Tillakaratne Dilshan was not too disappointed by his team's performance, and was full of praise for the home side.
"England batted well, put in a huge score to chase and it was not easy batting second to get 230," he said.
"We had to take chances and it didn't work. But that is not an excuse, we didn't bat well and we didn't bowl well - that is why we lost."
