"I like to sit in the stand to get a good view of the game but I've been on the move quite a lot recently because of our form," he said.
"At Charlton we have never had to call on things like a sports psychologist but maybe we will have to look at that. We seem to have a different attitude when we are away from home."
Holland was not his normally dominant self in only his third game back after fracturing an ankle on the opening day of the season against Bolton.
But he promises Charlton supporters he will now start to fire, starting with Wednesday's Carling Cup tie against Crystal Palace.
"It was always going to take a couple of weeks to get back to where I wanted to be," said Holland.
"I felt quite fit against Newcastle last week but match sharpness only comes with matches. It was the worst injury of my career. The nature of it meant I couldn't train with the ball for a long time."
Riise struck in the 51st minute at Anfield after Kevin Lisbie had blocked a header from Xabi Alonso and when Francis Jeffers gave the ball away 17 minutes from time, Garcia made him pay with a curled finish from 25 yards.
The defeat saw Charlton slip into the bottom half of the Premiership table.
