Sergio Ramos has declared himself fit after missing Real Madrid's first match of the FIFA Club World Cup, which he claimed "is like going on a camping trip".
Madrid have won the competition in two of the last three seasons and can retain their crown by beating Gremio in the final on Saturday.
Ramos did not play as the Liga and Champions League holders came from behind to defeat Al Jazira 2-1 on Wednesday.
But the Spain international defender could be involved from kick-off this weekend.
"I am feeling much better after a calf problem and then [the] back issue that I had," he told a news conference.
"But today I trained with no problem."

Of being with his team-mates in the United Arab Emirates for the mid-season event, Ramos added: "It is like going on a camping trip, a bit more professional, but with your mates spending lots of time together.
"We are eating together, in our free time together, and this union is one of the keys to success."
And Ramos claimed Madrid will not be taking their opponents, led by former Brazil international Renato Portaluppi, lightly.
"Gremio will not make it easy for us," he said.
"They have a coach who was also a player, so he can communicate what he wants from his team."
