James Tomkins has heaped praise on Crystal Palace teammate Mamadou Sakho.
The French defender has helped the Eagles win their last two Premier League matches with the assistance of clean sheets following his January loan move from Liverpool.
"Mamadou has come in and he's good to play alongside because he is so chilled and calm," Tomkins told Palace's official website.
"He has been brilliant since he has been here and it's a joy to play with him and I am enjoying my time as we learn from each other and let's hope it can keep going.
"From a personal point of view I think I have been playing well and it's so big to be keeping clean sheets in the Premier League and it's something the manager has always been big on and he has not changed one bit.
"He is trying to keep us as solid as we can and we will always have goals in us at the other end from our front three."
