Newcastle United boss Alan Pardew is wary about spending in January.

Pardew says there are no guarantees that Newcastle will be able to move swiftly in the window. He said: "It's a difficult window to get a good player when people don't want to lose their good players.

"It's not just difficult for us, it's difficult for every team. You locate a player, then they've got to get a replacement - and is another first-team going to let them go? There's a knock-on effect."
