article: John Carver is threatening changes when Newcastle face Liverpool on Monday night as he admits concerns remain over the character of his players. It is no secret United are planning a major overhaul of their squad this summer and 'personality' will rank high when it comes to identifying transfer targets. The trip to Anfield is Newcastle's first outing since losing a fifth straight Tyne-Wear derby and they have now won just twice in 2015. John Carver says his Newcastle players have a point to prove when they face Liverpool on Monday .

'We are going to need characters and I want to see some energy. I didn't see energy last weekend. We talked about out-working the opposition but they out-worked us again. 'So there's something not right within their DNA when it comes to a derby game. 'There's something not right within their make-up. No matter how hard you try and no matter what you try and do, it's an issue.' Carver has now seen his Newcastle team lose four in a row and fall into relegation danger . Newcastle were beaten in last weekend's Tyne/Wear derby by Jermain Defoe's stunning volley . That being the case, Carver says close-season recruitment will focus on mental attributes as much as physical. 'You've got to try and do as much homework as you can to find out about their personality,' he said. 'But with the amount of foreign players coming in now it's a tougher situation. 'I've done this in the past when I've gone to watch a player and sat with their fans. You can actually start having a conversation about them and try to find out a little bit about their character. What's he like? Does he get many red cards? Is he aggressive? Has he got a bit of a problem socially? All those little things help to build a bigger picture. 'But for now it is about finishing our season with pride and the players proving a point to themselves, because some of them are playing for their future.'
