Notts County manager Martin Allen says it is crucial he keeps his players relaxed for Saturday's vital home game against League One champions Brighton.
Notts have to win to be certain of avoiding relegation, although they could stay up even if they lose and other results go their way.
Allen told BBC Radio Nottingham: "I just want my players to enjoy playing.
"We saw Cardiff play Middlesbrough and be 3-0 down because the expectation and tension overcame their players."
Allen added: "It's not David Jones' fault [manager] or the players' fault - it sometimes does happen and I don't want that to happen to our lads.
"That was pretty painful for Cardiff and it can happen so we haven't built this game up into the FA Cup, World Cup or Champions League final.
"We have just trained and worked as normal and we all know there will be a lot of tension and excitement but I just want my team to go out and play some good football."
Notts (49 points), Walsall (48) and Dagenham & Redbridge (47) are all in danger of going down.
The Magpies are in the best position but goal difference could come into play.
Despite the consequences a defeat or draw could bring, Allen insisted he was looking forward to the game at Meadow Lane.
"It's a great game to be involved in for all the players all the staff and all the supporters," Allen added.
"This place will be packed and the atmosphere will be brilliant."
