Germany coach Joachim Low will contact Chelsea next week to ask for an explanation for Michael Ballack’s exclusion from their Champions League squad.
The Germany captain is currently recuperating from ankle surgery and was excluded from Chelsea’s 23-man squad for the group stages of the competition.
Chelsea insist they took the decision because they could not guarantee Ballack would be fit for the majority of their six group matches.
However, Low expects to have Ballack back for his side’s Euro 2008 qualifiers next month and cannot understand why the English club don’t share his confidence.
“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.”
According to Sport Bild magazine, Ballack was in Munich yesterday undergoing further tests to discover the extent of his injury with Germany and Bayern Munich team doctor Hans-Wilhelm Muller-Wohlfahrt.
Low said: “Michael cannot quite explain for himself why Chelsea have not nominated him for the Champions League.”
Ballack’s Champions League omission has fuelled speculation he will be sold when the transfer window re-opens in January but yesterday saw Chelsea dismissed such suggestions.
