Mangala didn't train today, his fitness will be decided on in the next 24 hours.
James Rodriguez is still working his way back to 100%.
Sporting Lisbon sit in 11th place and have only won 1 of their last 5 matches. Their home form is depressing as they have lost more matches at home (4) than they have won (3).
Porto are undefeated in their last 33 matches in the league and they still seem to be a dominant force in Portugal despite selling key players every year.
Traditionally a big rivalry in Portugal, these two sides represent the North and South of the country. Rivalries seem to neglect current form but with Porto going head to head with Benfica for the title, they just might be more motivated and fired up for the 3 points.
