Burnley boss Vincent Kompany praised Lyle Foster for his goalscoring return in defeat at Aston Villa.
The South Africa striker had missed several weeks due to depression.
Kompany said: "I honestly don't know how he does it. I really don't.
"We saw him when he was at his lowest point and it even makes me emotional to think about it because it was a real tragedy.
"To see him enjoying playing now with the team, I'm happy for him rebuilding his happiness and for me as a human not just a coach, it's beautiful for me to observe."
