The £11.5million summer signing from Ajax was a regular in the starting XI at the beginning of Tim Sherwood's reign but has struggled to hold down a regular place recently.
Olsen believes that it is only a matter of time before Eriksen starts playing again but respects Sherwood's decision.
He said: "Was it a surprise to see him left out? Yes, very much.
"But I accept what my colleague chooses and I don't know what happens in training.
"Nevertheless, when Christian has played he has shown he is a player who can make the difference. He is a creative player and he can play in different positions and Tottenham have used him in different roles.
"If he doesn't have a very good day he can always perform for the team because he works very hard, and that's very important when you play 40 or 50 games in a season. I've seen most of his games for Tottenham and I think he has done very well.
"Everyone who comes to the Premier League has to adapt to the different pace of the game. He has had a great technical and tactical education, but the next stop after that is to play in one of the top leagues in Europe. The name of the game in England is speed.
"He has shown from the beginning, though, that he is the kind of player who can do well in England."
