Will Grigg says that Wigan's recent win over Manchester City is even better and bigger than the occasion where they won the FA Cup in 2013.
Wigan were the team that stopped City from winning the same competition in 2013. But they were in a higher league at the time, which means the result was not as much of a shock.
Right now, City are the best team in England, and Wigan are two divisions below them.
"Yeah, I think it's bigger because we're a League One team and they are probably the best team in Europe at the moment," said the Northern Ireland international.
"It's got to be the biggest upset in a long time.
"They are flying, the quality of players they've got, they are an unbelievable side, scoring goals for fun. So for us to beat them on our patch is something special.
"It was an unbelievable performance — everyone to a man, including the substitutes. The gaffer and his staff worked really hard all week on a game plan. We have stopped probably the best team in Europe at the moment."
