Bayer Leverkusen veteran Michael Ballack admits Chelsea's transfer policy has left him confused.
Ballack was squeezed out of Chelsea last summer as the club appeared to go with a youth policy.
When Frank Lampard became injured last season, it was painfully clear that Chelsea were short of experience as their title challenge imploded.
So clear that owner Roman Abramovich has since spent £120million on players.
Ballack told the Mail on Sunday: "In Germany we say, 'What interest do I have in what I said yesterday?'
"Sometimes things go differently from the way you think. You have to change your policy. They put more young players in, to change the team a little. That's understandable."
