Franck Ribery feels Bayern Munich missed a trick by not bolstering their squad during the January transfer window.
The Bavarian giants remained quiet during the month with coach Jupp Heynckes failing to add a fresh face.
Ribery fears the club could struggle to maintain their title challenge if three team-mates are injured.
"I think it's a big problem for us if two or three players are injured," Ribery told Kicker.
"(Bayern) have no real good bench and don't have a really good second team. But I'm not the president, nor the manager, just a player."
Ribery insists he is ready to play on Saturday at Hamburg, but was struggling with the arctic temperatures at training in Munich.
"I still have pain, but I feel much better. I can play on Saturday," he continued.
"It's not much fun. It is brutal, even the warm-up is difficult in this cold. Minus 11 degrees, it's too much."
