Wigan earned a point in their 1-1 draw at home to Blackburn on Saturday through Rodallega's 53rd-minute header - his seventh Premier League goal of the season - after a poor first half. It was the first time this campaign the Colombian had scored and the side not won. Martinez said: "A few people were doubting whether the penalty he missed at Stoke (a fortnight ago) was going to affect his season but I think he showed he is extremely confident. "He is probably more powerful in the air than people give him credit for, he works extremely hard and he fully deserved his goal. "I'm sure he will carry on growing and fulfil his potential. "But if you look at the number of chances we have created I don't think we are too reliant on one player. "I think we have many dimensions in our play and can be a real threat. "Charles N'Zogbia is always a threat in the final third and once Jason Scotland scores his first he will also fulfil his potential as a goalscorer. "Jordi Gomez has the talent to score goals and has probably been trying to play people in, which is probably a lack of confidence."
