Belo Horizonte: Samuel Eto'o has missed two days of training with an injured knee and is battling to be fit for Cameroon's World Cup Group A game against Croatia, coach Volker Finke said.

"He has a problem with the right knee that he already had at the end of the season with his club Chelsea," Finke told a press conference yesterday. "He did not train yesterday nor today," the coach added.
