Cristiano Ronaldo has been forced to undergo a 'specially adapted' training schedule

Cristiano Ronaldo remains a doubt for Portugal at the World Cup, which starts next week.

The forward is suffering from tendinitis in his left leg as well as a left leg muscle injury, the Portuguese Football Federation (FPF) revealed on Wednesday.

Ronaldo has been forced to undergo "specially adapted, individual" training this week , and the FPF also said in a medical report that Pepe, midfielder Raul Meireles and goalkeeper Beto all trained separately on Wednesday as they recover from injuries.

"We hope that Cristiano is in good enough shape to play and to help the team," said team-mate, the Manchester United winger Nani. "He is going well, and he is relaxed about it.

"If for some reason [Ronaldo] is not there, whoever is there playing has to be confident in their ability to get the job done."

The world player of the year Ronaldo helped Real Madrid win the Champions League last month despite being hampered by leg injuries late in the season.
