Foxes increase lead
Riyad Mahrez's 17th goal of the season sent Leicester City eight points clear at the Premier League summit as Claudio Ranieri's men won at Crystal Palace on Saturday.
The Algerian winger tucked away a cross from Jamie Vardy in the 34th minute to earn Leicester a third successive 1-0 victory and bring a staggering title triumph a step closer.
Second-place Tottenham Hotspur can trim Leicester's lead back to five points if they beat Bournemouth on Sunday, while third-place Arsenal remain 11 points off the pace despite winning 2-0 at Everton.
"It sounds good [being eight points clear]. Our fans are singing a very good song about that," said Leicester manager Claudio Ranieri, whose side were serenaded with chants of "We're gonna win the league!" by their fans.
"But we have to stay calm because the Premier League is the same as every match. You don't know what will happen. We have to continue to push a lot because the Champions League is very close to us. Maybe in the next two matches I can say something more."
Elsewhere, Cesc Fabregas scored two equalisers, the second an 89th-minute penalty, as West Ham United were prevented from climbing to fourth place in a 2-2 draw at outgoing champions Chelsea.
The result left Slaven Bilic's side in fifth place, a point below Manchester City, who entertain Manchester United on Sunday.
After losing out to Palace goalkeeper Wayne Hennessey in an earlier one-on-one at Selhurst Park, Mahrez put Leicester ahead by steering in Vardy's drilled cross from the left.
Pardew admitted that he was "frustrated" by the result, but said that Leicester would make "worthy champions".
Knocked out of the FA Cup by Watford and the Champions League by Barcelona earlier this week, Arsenal bounced back with a one-sided victory over Everton at Goodison Park.
Danny Welbeck put Arsenal ahead early on, rounding Joel Robles to score after a neat build-up, and 19-year-old Alex Iwobi scored his first goal for the club in the 42nd minute after racing onto Hector Bellerin's pass.
Victory tightened Arsenal's grip on third place, moving them to within three points of Tottenham, and manager Arsene Wenger hailed his players for putting their recent disappointments behind them.
"It was a very significant win for us and a mental test," he said. I like this group, I like the mental attitude. It has been questioned and it hurts me. When you work every day with them, you see how much effort they put in.
"We are still in (the title race) in our minds and mathematically, yes, and we want everyone to be behind the team to give us a chance. We are ready for a battle."
Robbie Brady scored as Norwich City climbed out of the bottom three with a 1-0 win at West Bromwich Albion, meaning Newcastle United and Sunderland will both be in the relegation zone at kick-off in Sunday's derby.
