Crystal Palace midfielder Bakary Sako is delighted Mamadou Sakho returned in the summer from Liverpool.
The Frenchman signed for the club from Liverpool on a permanent deal this summer, having previously spent time on loan with the Eagles last season.
"I think he will be massive for us," said Sako to the Croydon Advertiser.
"He lifts the team up by his confidence and the other defenders gain more confidence as well, so he is a really big player for us."
