Carlton Cole is hoping to improve upon his England debut when he is next given a chance by Fabio Capello.
The West Ham United striker won his first senior cap as a late substitute in last month's friendly with Spain and came close to scoring in the 2-0 defeat.
He has kept his place in Capello's squad for Saturday's friendly with Slovakia and next week's 2010 World Cup qualifier against Ukraine at Wembley.
Cole is again expected to be on the bench, but is eager to live up to the increased expectations since making his England bow.
"I learnt a lot," the 25-year-old told the club's official website.
"There's a few things that I need to work on and hopefully I'll be a more complete player when I next get the chance.
"I've got high ambitions and new levels of expectation around me now.
"I just want to fulfil my potential and get to the highest my game [can get]."
