Crystal Palace secured their place in next season's Premiership with a 1-0 win over East London rivals, West Ham. The only goal of the game was a penalty scored by The Eagles' Mile Jedinak.
Crystal Palace manager Tony Pulis has said his side are now safe from relegation after their 3-2 win at Everton.
Goals from Jason Puncheon, Scott Dann and Cameron Jerome helped Palace move 10 points clear of relegation and boosted Arsenal's top four chances in the process.
Tony Pulis, who has overseen a remarkable turnaround since succeeding Ian Holloway in November, said: "I started at Hull and we had four points. Now we have 40.
"It is a remarkable achievement from the players - they have been absolutely fantastic. It is nice to say we are going to be a Premier League club next year with four games to go."
Crystal Palace's 3-0 win has further hampered Cardiff's chances of staying in the premiership. Two of the goals came from Jason Puncheon, while the other was from Joe Ledley.
Julian Speroni says he is desperate to extend his stay at Crystal Palace with his contract set to expire at the end of the season.
The Argentinian goalkeeper has made over 343 appearances for the south London club since joining in 2004, and has been a key performer in their battle to stay in the Premier League.
The 34-year-old said it was his "priority" to remain at Selhurst Park, adding: "I want to stay - and I think the club wants me to stay as well. We need to sort things out. When? I'm not really sure.
"There have been some talks but I don't think it's going to happen any time soon."
Crystal Palace midfielder Jason Puncheon has been fined £15,000 for comments he made on Twitter about his former manager Neil Warnock.
Puncheon posted a series of tweets - which he later deleted - following criticism of a penalty miss by Warnock, who had signed him on loan when manager at QPR in September 2011.
The row blew up after Warnock said: "There's no way I would've trusted him with a penalty. You've got to have somebody a little bit more cool, and he's not like that, Jason."
Puncheon then retaliated on Twitter with derogatory remarks.

As police approached the detached house, they noticed a man placing large bags inside a wheelie bin. He then ran off into Crystal Palace Park.
Sergeant Rob Goodwin from Bromley Police said: “This seizure represents a major and unexpected dent in the network of cannabis supply in the South East London area and was brought about through proactive local neighbourhood policing”.
Met Police have uncovered a huge drug factory in south London after driving past a house and noticing a strong smell of cannabis. When they went inside the property near Crystal Palace Park, this is what they found.
Four large rooms were set up to grow cannabis, with in excess of 500 fully grown plants inside.
The players have been fantastic, absolutely wonderful from the first minute we walked in.
We need to strengthen, we need to bring a bit more quality in with what club can afford - but we need to stay in the race by the time the window opens.
