Wigan FA Cup matchwinner Watson: Greatest moment of my career
The Wigan midfielder thought his season was over when he broke his leg against Liverpool in November.
Watson, 27, said: "It's unbelievable. The boys were fantastic from the first minute to the 95th.
"It's been a long six months for myself and it's a dream to come on and score the winner.
"Other than my children, it was the best moment of my life."
