Crystal Palace boss Alan Pardew says that despite increases in television income and the Premier League's relative financial muscle, clubs still need to be careful to avoid over-spending as transfer fees rise as well.

"We have to be realistic. Some of the figures being bandied about for good players, not great players, are massive," he said.

"We mustn't get out-priced. It's difficult for us. West Ham, Everton to pitch in and not expose ourselves. It's important we keep our heads and only do deals that benefit both clubs."
