Liverpool boss Jurgen Klopp praised goalscorer Sadio Mane after victory at Watford.
The goal was Mane's 100th in the Premier League.
Klopp said, "He's a top-class professional.
"He likes training – the physical part of it, the tactical side of it. He's a top, top professional. Yes, he's doing these kind of things in training as well. Our little problem is that we don't have too much time for training, so usually we recover and we don't play.
"That means we don't see that often in training because we just don't have time for it."
