German legend Bernd Schuster has attacked European champions Chelsea.

Schuster was reacting to Celtic's narrow defeat to Barcelona.

"I'm fed up of seeing these type of matches," said Schuster to ABC. "There shouldn't be teams like [Celtic] in the Champions League.

"We saw it last year with Chelsea. It was a very bad example for football and it is regrettable that they became champions.

"You see Celtic defending with 10 and almost snatching a point, and that's not fair."
