Chelsea boss Jose Mourinho values Belgium playmaker Eden Hazard at £200m after reported interest from Real Madrid.
Alan Pardew is weighing up chasing a big-name summer signing to boost Crystal Palace's profile.
Stoke City manager Mark Hughes has no plans to sell strikers Peter Crouch and Kenwyne Jones during the January transfer window.
Crouch has been strongly linked with a move away from the Britannia Stadium this month, with Crystal Palace and Queens Park Rangers both reportedly interested.
Jones, meanwhile, has been linked with a switch to Cardiff City after also reportedly being wanted by the south Wales club last summer.
However, Hughes is in no position to weaken his striking options and has ruled out Crouch or Jones leaving Stoke this month.
"We have good attacking players like Jon Walters and Marko Arnautovic," said Hughes. "But for out-and-out strikers we only have two, Crouch and Kenwyne Jones.
"So for us to even contemplate them going out is not the way we are thinking at the moment.
"There is no way I will weaken the group by allowing players to go."
