West Ham United play the third and final game of their German tour on Saturday, with goalkeeper Jussi Jaaskelainen hoping to end on a high.
The Hammers' sharpness visibly rose from their 4-1 defeat at Mainz to the 3-1 victory over Hamburg and the Finnish stopper wants that upward curve to continue.
He says pre-season is a vitally important time between the posts as stoppers aim to get back to their best.
Jaaskelainen explained: "The last couple of weeks have been a bit harder work and the games are getting tougher, but it has been a good pre-season so far.
"It's important for the outfield players to get their match fitness and from a goalkeeper's point of view it's more about getting your eyes in and getting your shot-stopping and reactions going.
"In the games it's all about the decision-making. If you make mistakes in the games, that's how you learn and get back to the level where you need to be."
The 38-year-old faces more competition for his place in goal this season with the arrival of Adrian from Real Betis, but he welcomes the challenge and says it will only help him improve.
He continued: "When you play in the Premier League, everybody wants to play there and competition is always going to be tough.
"The gaffer has added one more keeper to the first team and we've got four now. We need that because the season is long.
"You want to work together as hard as you can and as a keeper's union we look after each other and Adrian has settled in well."
