John Carver has indicated that Newcastle United are looking to strengthen their squad this summer.

Magpies boss Carver has revealed that owner Mike Ashley and managing director Lee Charnley are already planning for next season and has urged the frustrated supporters to stay true.

"I can understand that (the frustration), but we're already addressing it behind the scenes," Carver said. "They know what they have to do.

"Mike and Lee Charnley know what they have to do - and I'm telling you now, if I was sitting here and I thought they were giving me lip-service, I would say, 'Thanks very much, I'm off - I'm walking away from this'.

"But I'm not because I know what we have to do, I know what they're saying to me is right.

"I know what work is being done, and they've said it, they've gone on record. They've said that we need to bring players into this football club, first of all to boost the size of the squad, but also to improve the quality, to take us on.

"We can't stand still, because other clubs are not standing still and they know that. We have to go with them. And if we don't, you get left behind and they know that."
