Thierry Henry said the Stadium of Light was the noisiest atmosphere he had ever experienced during Sunderland’s derby win over Newcastle. Six days later, silence reigned. A sorrowful silence as thousands streamed for the exits in the wake of Crystal Palace’s fourth goal inside 14 second-half minutes. Sunderland strikers Steven Fletcher and Jermain Defoe can't hide their disappointment following defeat . A shameful silence as Sunderland’s players afterwards absorbed the shock of another embarrassing home collapse. But perhaps most damning was the sad silence of realisation from Dick Advocaat. When asked how concerned he was that the side he has inherited are in danger of the drop, he grimaced for fully 10 seconds before returning: ‘Worried? Yes, very worried.’ And he has every reason to be. Sunderland manager Dick Advocaat looks on as Sunderland are dismantled at home by Crystal Palace . The stands emptied during the second-half at the Stadium of Light as Sunderland conceded four goals . Exactly four weeks earlier Advocaat had watched from the comfort of his home in Holland as Sunderland trailed 4-0 at half-time to Aston Villa, a side who had scored just twice on the road all season. On Saturday, he watched from the discomfort of the touchline as Yannick Bolasie trebled his tally for the campaign with a devastating 11-minute hat-trick. The Congolese forward had earlier laid on the opener for Glenn Murray. Palace were ruthless and Alan Pardew, beaten in his last four Tyne-Wear derbies as Newcastle boss, had his revenge. Yannick Bolasie applauds the travelling fans holding the match ball after helping Crystal Palace to victory . Sunderland (4-3-3): Pantilimon 4.5; Jones 5, Vergini 4, O’Shea 3.5, Van Aanholt 5; Rodwell 5, Cattermole 4.5 (Bridcutt 64min, 5), Gomez 4.5 (Johnson 60, 5); Defoe 5, Fletcher 5, Wickham 6. Subs not used: Reveillere, Graham, Coates, Mannone, Buckley. Scorer: Wickham 89. Booked: Rodwell, Cattermole. Crystal Palace (4-4-2): Speroni 6; Ward 6, Dann 7.5, Delaney 6.5, Souare 6 (Kelly 35, 6); Zaha 7.5, McArthur 6.5 (Ledley 69, 6), Jedinak 6.5, Puncheon 7; Bolasie 9 (Sanogo 71, 6), Murray 8. Subs not used: Hangeland, Hennessey, Gayle, Ameobi. Scorers: Murray 48, Bolasie 51, 54, 62. Booked: Dann. Man of the match: Yannick Bolasie. Referee: Anthony Taylor 6. SUPER STAT: Sunderland have now lost the four matches immediately after their Tyne-Wear derby victories. Sunderland, though, had again given a depressing demonstration of how to surrender a football match. When your skipper, John O’Shea, is out-fought for a ball with the odds stacked in his favour — as he was for Bolasie’s second — then you know your problems have permeated the core of the team. Jermain Defoe, derby match winner the previous weekend, played as if he had been issued with an exclusion order from the penalty box. Advocaat said: ‘I can see for myself that we don’t create enough chances even though we play with three strikers. Even when we play with so many up front we don’t create anything and that means there is something wrong in the squad. ‘We showed we can do something against Newcastle but if we carry on performing like this then we have no chance.’ On this evidence, Advocaat is right. Sunderland will only be spared relegation by the shortcomings of others. They are not capable of saving themselves, as they did in miraculous fashion 12 months ago. Given that the season finishes with trips to Arsenal and Chelsea they are now working on a four-game rescue plan. Wilfired Zaha joins an ecstatic Bolasie (left) after the forward produced a stunning hat-trick in the second-half . For Palace and brilliant Bolasie, meanwhile, they are only looking up after four straight wins. And the 25-year-old credited Pardew following his first senior hat-trick. ‘That (goals) is what the manager has been demanding from me,’ he said. ‘He has been putting me right in the middle of sessions, even doing the lay-ups for me. Crystal Palace forward Zaha evades the attention of Sunderland striker Fletcher during the contest . ‘He has put sessions on that have been especially for the strikers, it’s been excellent.’ Pardew enjoyed seeing his side run riot. Murray headed them in front before Bolasie executed three swift breakaways. A league table from Pardew’s time in charge has Palace fifth. And he added: ‘We are a pretty young team and only need to add two or three to the squad and we could be a real force next season.’ As for next season for Sunderland, they can only hope they’re in the same division as Palace.
