Wijnaldum started both of Liverpool's Premier League matches this season in a withdrawn midfield role, tasked with protecting a back line featuring Virgil van Dijk but missing the experienced Dejan Lovren due to a pelvic injury.
The Brazilian was on the bench against West Ham on the opening day of the season but wasn't used by Klopp as the Reds cruised to a 4-0 win.
Brighton, meanwhile, sat deep for most of the first half and and only looked to attack on the counter, which was rare as Liverpool held on to possession quite well.
He told The Argus: "It's different because you know these are the sort of places that if you don't get it right then you can get beat big".
'You see Andy Robertson running around here at Melwood now and he's a completely different person to the one who was here in the first three months.
Fabinho then wasn't included at all as Liverpool earned their second win of the season at Crystal Palace earlier this week.
He is used to playing at a high level in France. It is not about who we play but about how we play. For sure it is not nice for a new player.
Liverpool have struggled with their defence over the last few years, but the former Red is of the opinion that having a commanding goalkeeper exudes confidence across the team.
"It's always good if the manager trusts you and it's always good if he tries to help you to become a better player, or in this case to make the next step".
Brighton kept a disciplined formation, frustrating Liverpool but creating little until a Pascal Gross header in the 88th minute forced a good save out of Liverpool keeper Alisson Becker. "I'm really working on the solutions and to ensure we are ready for all these games".
