Wigan face Liverpool on Wednesday and Martinez believes fellow Spaniard Rafael Benitez can turn things around at Anfield.
“Rafael Benitez has huge experience,” said Martinez. “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.”
“I still feel Liverpool will finish in the top four,” he added. “Look at their players. They have huge experience.
“You are not talking about young players or a young team. You are talking about Steven Gerrard, Fernando Torres, Pepe Reina and Jamie Carragher.
“It is probably the most experienced group of players in world football. What is happening at the moment will not affect them.”
