John Carver says Newcastle United need a clear-out this summer . The head coach is in danger of missing out on a permanent appointment following a string of desperate displays by his team , who were accused by Match of the Day pundit Phil Neville of having their flip-flops on . Carver hit back at that on Friday but fired his own warning to those who have performed so poorly . And with Sammy Ameobi , Ryan Taylor and Jonas Gutierrez out of contract in the summer , plenty of players will come under threat . John Carver says there needs to be a clear-out at Newcastle United in the summer . Sammy Ameobi ( left ) is one of many players whose contracts expire at the end of the season . ‘ They know there has to be a clear-out , ’ he said . ‘ It ’ s pretty obvious , to the man in the street and to the professionals — it has to be done . ‘ There are people out of contract , people who are not good enough — they know that. ’ Carver ’ s words are his strongest since taking over from Alan Pardew in January . The Magpies held a dressing-room inquest in the wake of last Sunday ’ s 3-0 surrender at Everton and the boss admits everyone — himself included — is fighting for his future at the club . ‘ We all are , ’ he said . ‘ That ’ s why I was a bit astonished when people ( Neville ) came out and talked about us being on the beach and wearing flip-flops . How can players do that when they know that everybody is playing for their futures ? ’ Carver ’ s situation has not been helped by the lack of player investment in the January window which has left him with just 13 senior players ahead of today ’ s visit of Arsenal . The Newcastle players applaud the fans after the disappointing defeat by Everton last weekend . Right-back Daryl Janmaat will deputise for suspended skipper Fabricio Coloccini at centre-back , despite admitting earlier in the week that he ’ d never played there . Carver said : ‘ I think he ’ s a great professional and he will deal with it . He understands the game , he is a full international . It ’ s another string to his bow and I think he ’ ll cope with it . ‘ He ’ s been great around the place . He ’ s such a character . He ’ s larger than life and he ’ s quite funny , but he ’ s a good professional with it . ‘ When we lost Mathieu Debuchy ( to Arsenal ) it was a blow but we replaced him with a better all-round player . ‘ But I must admit I ’ ve never been in a position like this ( with injuries and suspension ) and I don ’ t think anybody I ’ ve ever worked with has , either . ‘ I ’ m missing my best players and that ’ s how I look at it . With Papiss Cisse it ’ s like Tottenham being without Harry Kane . With Siem de Jong , it ’ s like them being without Christian Eriksen . ‘ It ’ s tough , but we ’ re not going to use that as an excuse and throw in the towel . Definitely not. ’ Darly Janmaat will captain Newcastle in the Premier League fixture against Arsenal on Saturday . The Dutch defender is deputising for Fabricio Coloccini who was sent off against Everton .
