Both players were on the scoresheet in the 5-1 triumph.
Assistant coach Aitor Karanka said: "It's not the norm that Higuain and Benzema play together, but they can. They did so in the second half of our previous match and they were both starters tonight. The team is more together and balanced when it works hard and covers a lot of ground. Both strikers are very dangerous up front. Benzema's injury doesn't seem serious at first. It happened during the first half; he strained himself and we took him off as a precaution."
