The two face-off this weekend.
"I can only comment on Luis, I can't comment on who is the better because all strikers bring different things to the game.
"His [Suarez’s] mental fitness is very strong,” added Rodgers.
"He is a player who, like most top players, can cope mentally and you have to because of the pressures they put on themselves to perform and the pressures of playing for a big club.
"But I think he has been admirable. He has never come in here any day not smiling and working hard.
"I'm very blessed and privileged to work with such a top player."
