The Spanish manager hailed the performance of his team in stifling home team's attacking players & with his squad now fully fit, is confident of securing a great escape
The victory pushed the Latics out of the relegation zone, with the Seasiders now replacing them in the bottom three, although there is still only a one-point gap between them and the drop-zone.
Martinez, however, is buoyant and was full of praise for his side who have been written off by many as certainties for the drop.
“It was a huge, huge victory," he said to reporters after the match.
“More than anything before the game we knew the points were important, the result was important, but more significantly if we could perform under the pressure and expectations of today’s fixture.
“And I was so, so pleased in the manner that we understood what we had to do, in the manner that we controlled Blackpool.
“I’ve seen Blackpool many times this season and I haven’t seen teams who have been able to cope with their real threat going forward, and that was probably the real pleasing aspect.
“In many ways, I have said it before that the players have been showing a great level in the last eight games without getting the wins and that is why today probably is even bigger than a normal result.
“It means a lot after eight or nine weeks of hard work. I am extremely proud of the players today. I felt we deserved the win and it is a very, very important step forward but there is still five [matches] to go now.”
Martinez was pleased with the work-rate of his team as they hassled Blackpool into conceding an early goal.
“The reality is we had to work really hard today off the ball,” he added.
“You know that they have players who can switch the play really well, technically outstanding footballers.
“I felt that we got the reward out of that, being very disciplined, very well-organised and working extremely hard.
“Then, once you get into that position you need to finish it and it was great to see two clinical finishes from Charles N’Zogbia and Hugo Rodallega.
“I felt that we looked a threat when we were going forward and we always felt that we were composed in our defending and we coped with their set-plays really well.
“For me it is a very significant victory.”
Martinez saved his highest praise for Charles N’Zogbia, who scored the second of Wigan’s three goals.
He said: “There has been a lot of talk about Charles. He is an exciting player, he relies on his raw talent and gets in great one against one situations.
“But today more than anything, if you want to highlight something about Charles’ performance, it was his work-rate off the ball and the manner that he helped his team-mates and how he kept the ball further off the pitch for us to get out of the defending positions.
“Overall, it was a very good performance.”
The Spaniard is confident his team can escape the drop and highlighted the strength of his squad as proof that they are capable of surviving.
“We have great competition in the squad," said Martinez.
“I can guarantee you that this is the strongest that the squad has been all season. We’ve got no injuries and only Maynor [Figueroa] is suspended.
“There’s a lot of frustrated players at the moment and they want to help.
“We were bottom of the league before today’s game and in a club like that to have everyone fit and available and wanting to help the football club I think shows you the high standards that we’ve got."
