Martinez has backed his countryman ahead of his side's visit to Anfield tomorrow and says Benitez has been unlucky with injuries.
"Rafael Benitez has huge experience," said the Wigan boss.
"He has been in this situation many times before and he will find the answers. It is just a matter of time.
"What tends to happen in these situations is that you get a little bit of a snowball effect because, before the start of the season, expectations were really high.
"But any squad would be damaged but the number of injuries they have suffered to key players.
"The quality is there. They showed that in the first half against Arsenal yesterday. They have world-class players and they will turn the corner. I have no doubts about it."
