France manager Didier Deschamps has admitted that his team will need to pay "special attention" to Cristiano Ronaldo in their upcoming international fixture against Portugal.

The 29-year-old has scored 17 goals in 11 games for Real Madrid this season and bagged a hat-trick during his club's 5-0 win over Athletic Bilbao on Sunday.

"This is a player who has a very high efficiency," he told reporters. " The people who will come to the stadium will be happy to see him. I do not know if he will play or how long he will play since Portugal has an important game three days later.

"It takes a special attention, of course. In one against one, he manages to make a difference. Limiting his influence to his team is something important but it also allows more freedom for those who are around him."

Ronaldo is Portugal's all-time leading scorer with 50 goals from 114 appearances.
