Why did Eriksson play Andy Johnson out of position?

"I know he’s better in the centre, but we decided to stick with the system we started with”- Eriksson

Andy Johnson plays in England for Crystal Palace and earned his first cap last night in a friendly against Holland.

Why England manager Sven-Goran Eriksson played Johnson out of position doesn’t make sense to me.

My logic on this is that Johnson plays alone up front all the time at Crystal Palace and would have felt very comfortable in that spot. Instead the coach chose to experiment by having Johnson deliver crosses instead of receive them. To go for the win, a fresh, in form striker in position would have been the right thing to do.

Sven-Goran Eriksson didn’t go for the win. Yes, a friendly is a friendly, but why bother watching if you see the coach’s experiments sacrifice the teams chances?
