Fabio Coentrao asks out of Portugal's World Cup squad after 'exhausting' season

An "exhausted" Fabio Coentrao has asked to be left out of Portugal's World Cup squad this summer.

Coentrao, who is on loan to Sporting Lisbon from Real Madrid, played in 43 matches over five different competitions this season

The 30-year-old left-back wrote on Instagram that he has informed Portugal boss Fernando Santos he did not believe he could meet the demands of a World Cup this year.

"In the last week, after a lot of thinking, I told the national team coach that, after a very exhausting season, I feel I don't have the necessary conditions to represent the national team," he wrote.

Coentrao has made 52 appearances for Portugal and has twice participated in the World Cup. He was kept out of his country's Euro 2016 triumph, however, because of a hamstring injury.

"I would never turn my back on my country, and I hope I can return to represent our national team more times in the future," he wrote. "Until then, I am and will always be cheering from afar, see you soon. Good luck everyone."

Also missing out on the World Cup will be Renato Sanches, who was voted best young player at Euro 2016 but has since struggled for form and fitness.

Sanches, 20, moved from Benfica to Bayern Munich after the tournament, but he failed to impress in limited appearances and was sent on loan to Swansea City, where he continued to underwhelm.
