Crystal Palace have announced the signing of Mamadou Sakho from Liverpool FC on a permanent deal.

The France international, who spent the second half of last season on loan at the Selhurst Park but the possibility of a full-time move initially looked uncertain as Liverpool were demanding £30million for the centre-back.

Now, the 27-year-old defender has put pen to a paper on a four-year deal with the Eagles.

“I am really happy to be here because I have some friends here,” the Frenchman told the club’s website. “I loved the challenge last year; it was difficult but beautiful and it’s why this summer I thought that Palace was the best choice.

“I am really excited about playing for the Palace fans again, but in football the past is the past and you need to think about today and tomorrow.

“Last year we did a good job and we need to prove that again and have a good objective. If we put all of our power together, we will have a great season.”

Sakho joined the Reds from Paris Saint-Germain in 2013 and has since gone on to make 80 appearances for the Merseyside giants.
