Wilfried Zaha has praised the work ethic of Crystal Palace teammate Aaron Wan-Bissaka.
The 20-year-old impressed in Saturday's 2-0 win over Fulham after manager Roy Hodgson picked him ahead of the more experienced Joel Ward.
Zaha said: "He's very receptive to information. He's very serious about his football. I've seen him get better over the last six months.
"How much better he can get, who knows but at the moment we're more than happy with him because he's doing everything we need him to do on the field and that's proven against a team of Fulham's quality."
