UWE Rosler admitted Jordi Gomez has ‘the X-Factor’ after seeing the Spaniard win the game against Charlton with virtually the last kick.
Latics had trailed from the third minute against a determined Addicks side - a lead they held until two minutes from time.
After hammering on the door for the whole second period, Latics finally broke through when Josh McEachran played in fellow substitute Marc-Antoine Fortune.
And with 90 minutes up, Gomez - who had only appeared off the bench 16 minutes from time - curled a magnificent free-kick round the wall for a dramatic winner.
“I had toyed with the idea of starting with Jordi, and I spoke to him before the game,” revealed Rosler.
“He was obviously disappointed not to start, but I knew the game would be scrappy - with not much room - and I wanted to be able to bring him on.
“Jordi responded in the perfect manner, like the true professional he is.
“He really wanted to prove me wrong, and he did just that, both with the way he played and the goal that scored.
“I’m very happy for him. He proved a big point to me to perhaps start him more.
“Jordi has the X-Factor - and he proved it again.”
The nature of the defeat was undoubtedly harsh on Charlton, who had led through Marvin Sordell and hit the bar through Reza Ghoochannejhad in a promising opening 20.
Callum McManaman saw a shot of his own strike the woodwork just before half-time, and after the break it was all one-way traffic.
Nicky Maynard saw a seemingly good goal disallowed shortly after the restart, and Rosler had started to worry the goals were never going to come.
“I thought it was going to be one of those days where you have total domination and just can’t make the breakthrough,” the Wigan boss added.
“Especially after we had a perfectly-good equaliser disallowed at the start of the second half.
“I’ve seen it again on DVD, and Nicky Maynard (below) is clearly two yards onside when the ball is first played in.
“Then, in the second phase, the ball comes back off the Charlton player, so there was no way he could have been offside.
“I just can’t believe the linesman didn’t see that from the side.
“But there was justice, somewhere - and we deservedly came back to win the game.”
