Kuranyi walked out on the national team when he was left out of the 18-man squad for last Saturday's World Cup qualifier against Russia, while Frings expressed his disappointment at being left on the bench.

Low claimed it was "normal" for his team to change for every match and expected players to be disappointed.

"We have got to move away from the concept of a Germany national team which remains the same 11 players for the duration of a season," he said.

"If you just look at Manchester United or Chelsea you see that you now need 20 to 22 players and that means every week that some will have to sit on the bench or in the stands.

"That is absolutely normal when you have 20 to 22 players who can all play at a high level, like we do."

While Low could not condone Kuranyi's decision to abandon the squad on Saturday, he praised Frings' reaction.

"Frings was obviously very disappointed when I informed him on Friday that he would not start the game, but he reacted very well," added Low.

"Torsten motivated the team a lot before the game on Saturday and spoke with all the players.

"More than anything, at half-time he came in and had words with each player before going out to get warm.

"I hold Frings in high regard because he has played over 80 international games and, since I have been involved here, he has always given everything for the team.

"That is why Frings is an important player for us."

Low also hinted strikers Lukas Podolski and Kuranyi should follow the example set by Frings.

"You just think of the discussion as to why Podolski is not playing at Bayern (Munich), but why this discussion?" he said.

"You need 20 people to achieve your aims and you have got to be professional about it.

"A team is not 11 players anymore and that is also the same with Schalke, if they have aims and want to win the German league title."
