Romelu Lukaku kept Everton in the FA Cup with a late equaliser at Goodison Park against West Ham, and the Belgian striker will now look to fire in the goals which will take his team to the fourth round when the replay at Upton Park takes centre-stage on Tuesday.
Everton looked dead and buried heading into the final moments of their third round tie at home against West Ham a few days ago, but Lukaku kept those trophy hopes alive with a brilliant goal to force the replay after James Collins had given the side from London the lead early in the second half.
"Draws are an emotionally tricky result in terms of how you feel about them," said Roberto Martinez. "It's still only a draw but when you are the team that gets the equaliser late in the game, it can feel like a victory. In the same way, when you concede late on, it can feel like a defeat.
"We're pleased we have a replay to play. It was a proper cup game and I feel Tuesday will be exactly the same -- two teams wanting to win and to score goals; that will make it really open.
"We always enjoy going to Upton Park and with our sold-out allocation once again, it's one we look forward to."
Everton are not having the greatest of seasons in the Premier League, having picked up just 22 points from 21 matches so far, but the Toffees will take heart from the 1-1 draw against champions Manchester City at the weekend – again courtesy a late equaliser, this time from Steven Naismith – which snapped a four-match losing run in the Premier League.
"This week has been really positive for us," added Martinez. "In the way we are as a team, we're very similar to where we were two weeks ago but from a psychological point of view we are getting confident again.
"The performance against Manchester City has given us a lot of belief. That's important but we're facing a West Ham side that are strong. They have a real variety of personnel that can be played in different systems. That's made them a difficult side to face.
"The goalscoring threat from West Ham can come from very little. They don't need much to put you under pressure in your own box and that's something we need to be well aware of. I'm expecting a terrific game of football."
West Ham have seen their terrific start to the season slow down a little bit of late, with the Hammers winless in their last five matches, four of them in the Premier League. However, despite that momentum being quelled a little bit, manager Sam Allardyce firmly believes his side have all the confidence and ability in the world to topple Everton and go on an FA Cup run, having lost out on that opportunity last season.
"We were very close when we played at Everton," said Allardyce. "Everton getting a draw against the champions Manchester City shows how good we were.
"Tomorrow won't be cut and dry, we know it will be a hard game. When the opportunities come, we need to take them because there's it'll be played to a finish. We have to make sure we come out of it without having wasted our energy."
