Alan Pardew has admitted his summer spending plans are up in the air until the futures of key squad members are clarified.
Pardew has guided Newcastle to safety in the Premier League despite being shorn of the services of Andy Carroll following his sale to Liverpool in January.
The Magpies boss has £35 million burning a hole in his pocket and is keen to strengthen in a number of areas, but his priorities are to thrash out new deals with Joey Barton, Jose Enrique and captain Kevin Nolan.
"I haven't put a figure on how many players I want because it depends on the renegotiations of players we have," Pardew said. "Joey Barton, Enrique and Kevin Nolan all need contract deals sorted out - and there are others I won't mention that we still need to secure."
"We've made contact with a few clubs about their players, I think that's important," he said. "There's a lot to be done but the process has started. Our chief scout Graham Carr and his team have been very much on the ball and understand exactly where the European market is and the targets we have."
