Opta's statistical model now projects a 99 percent probability that either Tottenham Hotspur or West Ham United will occupy the Premier League's final relegation spot, with Spurs carrying a 61.01 percent likelihood of going down and the Hammers at 37.98 percent.

The projections sharpened dramatically Friday after Nottingham Forest demolished Sunderland 5-0, moving Vitor Pereira's side to 39 points, eight clear of 18th-placed Tottenham and six ahead of 17th-placed West Ham.

Forest and Leeds, sitting on 39 and 40 points respectively, have each been reduced to below 1% relegation probability by Opta. No team has been relegated from the Premier League with 39 points since Birmingham and Blackpool both went down on that total in 2010-11.

Tottenham have not won a league match since last year and face remaining fixtures against Wolves, Aston Villa, Leeds, Chelsea and Everton. West Ham, who have won two of their last five, still must face Everton, Brentford, Arsenal, Newcastle and Leeds.

"You are asking Tottenham to win four games," said former England midfielder Jamie Redknapp. "Back-to-back wins and it all changes."

Mathematically, Tottenham could theoretically reach 46 points, but only by winning all five remaining matches.

Forest's commanding run, unbeaten in eight across all competitions, was highlighted by four goals in a devastating first-half stretch against Sunderland. Morgan Gibbs-White extended his outstanding form to seven goals in seven games, while Chris Wood returned from a knee injury to get on the scoresheet.

"It isn't enough," Forest coach Pereira insisted after the victory. "We need more points, we need to win more games."
