Before a match, Lammens writes about the opposing team's strategy and how they might try to pressure him. He also notes key points he needs to remember during the game.

Lammens emphasizes the importance of being a well-rounded goalkeeper. He takes pride in his ability to stop shots, come out for crosses, and distribute the ball effectively. He also highlights his ability to play with both his left and right foot, which makes it harder for opponents to anticipate his movements.

However, Lammens notes that coming out for crosses can be challenging, especially in the Premier League. He still prefers to do it, but he also needs to be mindful of his own safety.
