Germany boss Joachim Low is to contact Chelsea next week to ask them to explain Michael Ballack´s exclusion from their Champions League squad.
The Germany captain is recovering from ankle surgery but Low is confident of having him back for his side´s European Championship qualifiers next month.
"For us, Chelsea´s decision is unfounded," said Low. "After the internationals, I will call Chelsea because it would certainly be interesting to find out why Jose Mourinho has made such a decision. At the moment, nobody can quite understand it."
