German legend Bernd Schuster has attacked European champions Chelsea.
"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."
