Oldham Athletic boss John Sheridan hailed his FA Cup heroes, admitting that the win at Everton was "the best result I have had as a manager."
Sheridan said: "To come to a Premier League ground against a team who are really flying at the moment was a great performance.
"I told the players to really enjoy the occasion, because things like this might not happen to them again.
"I was so pleased and proud of them.
"I believed we could get something from the game, we have won seven on the trot away now, so we are doing something right.
"I can't praise them enough. The togetherness was outstanding, kids and experienced players."
Sheridan did not believe Everton put out a weakened side, adding: "I have watched Europe a few times, I have seen them in Europe, and I knew it was going to be a massive test for us whoever they put out."
