The goalkeeper has played club football for more than two decades and his been a mainstay for Australia since his debut in 1993.

Schwarzer is still excelling for club and country at the age of 39 and, despite having played 27 Fulham matches already this season, refuses to acknowledge tiredness as an excuse for players.

"It's one of those things," said Schwarzer, who faces Liverpool at Craven Cottage on Monday.

"When people ask me about the national team and the amount of travelling and the number of games that we play, for me it's all about a mental approach and a mind set.

"You've got a long time to recuperate after you've finished playing.

"When you talk about the demands of the English Premier League, yes they are tough.

"But you're playing in one of the best leagues in the world and do you expect any different?

"I don't have to play for my national team. I want to play for my national team, if I'm selected, as much as possible. It's an honour.

"If anyone asks me if I want to play a game of football or a manager asks me if I want to play I will always respond in the same way because I want to play as many games as I possibly can."

Schwarzer also believes end-of-season fatigue is no excuse for the England team at Euro 2012.

"It is interesting because if you look at the players who have played for England, there are a lot of players who have been rested a lot of the time as well," he said.

"They're playing for big clubs with big squads and there's a lot of resting going on between games as well, which is great.

"That gives these guys the maximum opportunity to recover and be right for the next game.

"I think as well it depends on the atmosphere of the group of players.

"[If you look at 2010], at the back of the season when we got to the Europa League final and I played seventy games, I then went to a World Cup.

"If that's not enough to lift anyone then nothing in football will be enough to lift you.

"It's the environment. When I get to go away with the national team it's a completely different environment, it's a different buzz and you're raring to go.

"You want to be successful. You want to be together as a team as long as possible."

Schwarzer made his 13th Europa League start of the season in Thursday's 1-0 defeat at FC Twente.

Fulham have struggled to cope with the exertions of playing on a Thursday night and then the following weekend, but Schwarzer remains philosophical on its impact.

"It can be tough at the beginning because you can get frustrated if results go against you a little bit, but you've got to take a long-term approach," he said.

"You've got to look at it and think: 'OK, well the games may have gone against us this weekend, but we've got 38 league games to play this season and cup games as well'.

"The league is obviously the number one priority and there are enough of us in the squad at Fulham who are experienced enough to realise that and we make sure that everyone is aware of that as well."
