Liverpool left-back Alberto Moreno says teammate Mohamed Salah only trains at 20 percent of his capacity for "fear of getting injured."
Salah has enjoyed a superb season with Liverpool since joining from Roma in a transfer deal worth up to €50 million last summer, scoring 43 goals in 49 games in all competitions.
"He is a great guy, very humble, very calm," Moreno said of Salah to Onda Cero radio.
"I don't think on the pitch there is any need to explain what he is like because everybody has watched him play and the numbers are there for everyone to see. He is having a fantastic campaign.
"I don't think he is the same in training, he trains at 20 percent because he fears getting injured and in order to be at the top form in the games."
Salah started against his former club in a 4-2 defeat in Wednesday's Champions League semifinal return leg, a result that gave Liverpool a 7-6 aggregate win and a place in the final in Kiev where they will face Real Madrid.
The Egypt international scored twice and set up another two goals in a 5-2 win in the opening leg at Anfield.
Moreno, meanwhile, says his team has a lot of respect for Real Madrid, who eliminated Bayern Munich and are now just a win away from a third straight title in the competition having reached their fourth final in five years.
"I've faced them [Madrid] more than once, it's very complicated," said Moreno, a former Sevilla player.
"They are very good players, they have a great team. But they are in the same position as us. We have very dangerous players up front like Salah, Sadio [Mane], Roberto [Firmino]. We have a great side to fight for this Champions League."
Moreno is hoping to play his part in the final in Kiev on May 26. The Spaniard has struggled to hold onto a starting place since sustaining a left-ankle injury in December. In fact, he has only made four starts in all competitions for the Reds in 2018.
"I got injured against Spartak Moscow in December and the truth is that it took me two months to recover from my ankle injury," the 25-year-old said.
"I returned to play and did well. I'm not happy with the situation but it was down to an injury and not a decision that he [Jurgen Klopp] made.
"What every player wants is to play and have minutes. But right now, this is not the time to think about that but rather to enjoy that we are in a Champions League final, which doesn't happen often."
