Captain Aaron Ramsey insists there is still more to come from him as he and Wales look to end the season on a high against Mexico.
The Arsenal midfielder has been a key figure as Wales have climbed from 117th in the FIFA world rankings to their current position of 41st, while also helping the Gunners recover from a poor start to record a third-place finish in the Barclays Premier League.
He said: "This was my first full season. I started off well, I had good games and bad games and I have probably got a bit tired towards the end. But I'm happy with the way things have gone this season. Obviously I know there is a lot more to come from me as a player. I'm still learning but on the whole I've been pretty pleased."
The 21-year-old will make his 50th appearance of the season when he leads the Dragons out at the 82,000-capacity MetLife Stadium, a major step up in workload for the former Cardiff youngster, particularly for his first full campaign since his horrific leg break in February 2010.
Ramsey also had to cope with the death of Gary Speed, the man who made him Wales captain, in November, but says the squad are ready to continue the excellent form they showed under their former boss with Chris Coleman now in charge.
He added: "My leg is fine. The demands in the Premier League are extremely high and you have games every three or four days. I think at certain times that took its toll on me. That was to be expected. I'm sure I will be better and more aware of it next season.
"With Wales our last game was an emotional occasion and the result reflected that, and we want to pick up where we left off from the Norway game (a 4-1 win in November) and keep progressing and improving ahead of the World Cup qualifiers.
"The way we want to play is the same, Chris Coleman has brought in a few things he wants to add which he feels will make us stronger. We have been taking that on board and hopefully we can show a few of the things we have been working on on the pitch tomorrow."
Ramsey's performances have led him to being tipped to land a place in Stuart Pearce's Team GB squad for the Olympics this summer, although the Football Association of Wales remain opposed to Welsh players being selected due to concerns over their status within FIFA.
But the playmaker insists Pearce's upcoming selection is no distraction. "I am away with Wales now and I am concentrating on this game, hopefully it will be another progression for us," he said.
