Uwe Rosler admits Jordi Gomez taught him a lesson after being left out of Wigan’s line-up.
The Spanish star was dropped for the Latics’ trip to Middlesbrough last Tuesday and could only make the bench against Charlton.
But he responded in fine style by curling home a beautiful 90th-minute free-kick to bag the three points, 16 minutes after coming on as a sub.
And Rosler beamed: “He was disappointed not to star, but he responded in a fantastic manner – like a true pro.
“He really wanted to prove me wrong, and he did that in the way he played and in the way he scored.
“He proved a big point to me – to start him more.”
Incredibly, in form Wigan trailed Charlton, who haven’t won away in the league since November, for 86 minutes.
Marvin Sordell put the Addicks in front with first attack of the game by sliding calmly under Ali Al-Habsi.
Charlton new-boy Reza Ghoochannejhad then hit the bar, before the Wigan onslaught started.
And after smashing the woodwork twice themselves, they equalised on 89 minutes when Uwe Rosler’s two other subs, Josh McEachran and Marc-Antoine Fortune combined for the latter to score.
And moments later, Gomez stole his last-gasp winner.
The result leaves Charlton stranded in the relegation zone, and defender Michael Morrison said: “It is very disappointing – when we were so close to winning the game – to get nothing out of it.
“But there’s no need for any panic, although the quicker you can get the point on the board the better.”
