Marcelo set to be fit for Mexico clash

Brazil have received a boost ahead of their round of 16 duel with Mexico with news that defender Marcelo is expected to play after overcoming a back problem.

The Real Madrid left-back was forced off in the 10th minute of Brazil's 2-0 victory over Serbia on Wednesday after suffering a back spasm.

Brazil team doctor Rodrigo Lasmar said the 30-year-old is making encouraging progress as he undergoes daily physiotherapy at the team's Sochi training base.

"We are going to observe him a little more to see how he is in the next 24 hours," Lasmar told reporters on Friday.

Monday's clash in Samara will be the fifth time that Brazil and Mexico have met in the World Cup finals. Brazil have won three of the teams' previous encounters and there has been one draw.
