Wigan manager Roberto Martinez has warned his team to approach their crucial game against West Ham the same as any other and not to "play the occasion".
Second-bottom Wigan host Avram Grant's basement dwellers with both sides in trouble and running out of games at the bottom of the Barclays Premier League. Depending on results elsewhere this weekend, defeat for the Latics could see them slip three points from safety while West Ham will be doomed to the drop should they fail to win.
However, Martinez is urging his team to take a calm approach rather than panic about the outcome and he said: "To only think about getting a result would be a big mistake."
He added: "In moments like this you start talking about getting results and what a big football occasion it's going to be.
"It's true that it's a key moment in our history but you can make the mistake that you want to concentrate on the result so much that you don't know how you're going to get it.
"I think now we need to realise what we're good at and make sure that we understand who we're playing against.
"We need to understand that to win a football game you need to perform well and if you perform well you can get the result. In these big occasions you can play the occasion and not the game and that would be a big mistake."
The former Swansea boss also urged his side to be wary of the Hammers, despite their position.
He added: "We have to be aware of the quality that West Ham are going to bring to the game because they are in real need of points exactly like ourselves. And if you look throughout their squad, the experience and talent that they've got, it doesn't really go with the position they are in the table and we'll have to be very careful in that respect.
"The best way to play the occasion is to be aware of what West Ham will bring."
