Crystal Palace boss Roy Hodgson admits injuries to key players are proving difficult to manage.
Hodgson was speaking after their 0-0 draw with Nottingham Forest.
He said, "It's unlucky of course. We think very carefully about what we do in training. Last week, we had two very tough matches in Manchester.
"Eberechi Eze has a really serious hamstring injury and Michael Olise has had surgery.
"When you are missing two creative players of that quality, I don't care whether you are Crystal Palace or Manchester City or Liverpool, you take those out and you lose something so we're going to have to keep fighting on with what we have at the moment and getting the best out of them."
