Monday night's 1-0 home defeat to Manchester City has left Wigan at the foot of the Premier League and once again staring at an uphill battle to preserve their top flight future.
With only one win and 10 goals at the DW Stadium all season, it is easy to pinpoint an area where dramatic improvement is required.
And Rodallega could certainly help as, so far, the Colombian striker has found the net just once in 16 appearances.
Martinez is not the kind of manager to demand more goals from the 26-year-old, the Spaniard is too committed to the team ethic of collective improvement for that.
However, after having no pre-season due to his Copa American campaign, then a short period out of the team due to injury, Martinez detects his number-one striker is starting to find his form again.
"Hugo looks refreshed," said the Wigan manager.
"He had a really tough start to the season because he did not have a proper break. Then he had a little bit of an injury and we missed him for a little bit.
"It is only in the last three weeks that he has been himself and enjoying his football.
"At his best, he is a big asset for this club. He is capable of opening things for us. We are really pleased with the level he has shown in the last three games."
Wigan do need goals, though, as only five players have scored more than once, with Franco di Santo and Jordi Gomez leading the way on four each.
"It would be unfair to say we rely on Hugo's goals," said Martinez.
"He is a goalscorer but only in the same way, Conor Sammon, Franco di Santo, Victor Moses and Albert Crusat are players who can chip in.
"Goalscoring is an overall team responsibility, just like keeping clean sheets.
"I wouldn't rely on one single player. It would be too easy for the opposition to stop."
Nevertheless, finding someone who could hit the net on a regular basis would offer Wigan some hope of emerging from their present plight.
And, with two weeks remaining before the transfer window closes, the hunt for new players is on.
"We try to use every window to our benefit," said Martinez.
"I do think we could do with a couple of additions and whilst we accept this is a difficult period to get players, we have to work as hard as we can to strengthen."
