Chelsea winger Andre Schurrle says they'll be ready for Arsenal and Mesut Ozil in tonight's Capital One Cup tie.
Schurrle, though, is unsure if he'll be in the line-up.
"It's no surprise for me that Mesut is playing so well," Schurrle said.
"I'll be happy to see him and Mertesacker because we have a good team spirit in the national team and we are all good friends, but tomorrow, for 90 minutes, there are no friends.
"The manager will change many positions but we have high quality in every member of the squad and there will be no problem for us.
"I think Arsenal will change their players, too, and it's going to be a good match.
"I am very happy to be a part of our squad, and with a team like Chelsea you want to win every competition you are in, so we'll do everything tomorrow to win the match."
