The Hammers, who have lost each of their past three matches, sit 18th on the table going into the final day, two points behind Tottenham, which hosts Everton.

Only a win, coupled with a Spurs loss, will be enough to keep the Hammers in the Premier League and avoid its third relegation from the competition.

Nuno acknowledged that the fans will likely be keeping up to date with what happens at Tottenham Hotspur Stadium, but he does not want the players to get swept up in that.

"Everybody's going to be aware of what's happening in the other situations; we can't get away from that," he said.

"What I hope is that our players ignore what’s happening elsewhere and focus on their tasks on the pitch. This is more important than anything.

"Every game in the Premier League is like a cup final, but yes, for sure [this is one of the biggest games of my career]. Everything is going to be decided.

"Right now, there's nothing in our minds other than Sunday. Afterwards, it will be the time to start thinking about that."

Leeds, meanwhile, has been assured of its safety for a couple of weeks and heads into the match 14th on the table, having gone unbeaten in its past eight games.

It still have one last chance to push up the table if it can win at London Stadium, and manager Daniel Farke is particularly keen to finish the season on a high.

"After a fantastic season for us and so many setbacks, we want, of course, the best possible finish of the season," he said.

"The best possible finish is always a good performance, good result. Each and every position on the table counts, each and every point counts.

"For that, we are also hungry to extend our unbeaten run and also hungry to finish as this group of players also deserve in style, with good performance, and yeah, if possible, also three points. If not, then perhaps one point. But of course, we want to stay unbeaten."
