Bayer Leverkusen general manager Rudi Voller insists he does not have any regrets about signing Michael Ballack this summer.
The Germany international moved from Chelsea on a free transfer in July while suffering from an injured ankle which kept him out of the World Cup.
He has since gone on to make four appearances for the Bundesliga outfit before fracturing his shinbone in Leverkusen's 2-2 draw with Hannover on 11th September.
He was expected to return in late October but will now be sidelined until after the winter break after the injury turned out to be more serious than first thought.
Despite his injury-plagued start back with Bayer, Voller insists he has no regrets in signing the 34-year-old.
He told BILD: "No one was to know he would get injured so seriously, he is the sort of player we were missing out on last season in different kinds of aspects.
"He can stand up and fight and he has to fight his way back into action now, then he is going to have some good years left."
Ballack has not featured for the national side since March, when he picked up his 98th cap in the friendly defeat to Argentina.
Voller believes the midfielder's future is in his own hands, saying: "Michael will decide everything on his own with his performances. It will be fully his decision whether to be back in the Germany squad or not."
