Sam Allardyce has admitted he is struggling to compete with Chelsea in the transfer market.
As well as their spending power, Allardyce believes players are lured to Chelsea by the prospect of living in the capital and being involved in the UEFA Champions League.
"You try all you can and use all the weight behind you to persuade players to come to you," he told the News of the World.
"But when you are competing with Chelsea it makes life extremely difficult, even for Newcastle.
"There are the lures of London, Champions League football and the fact they play 56 to 60 games a year.
"Any player there can play 25 to 30 matches because of their huge fixture list every year, so it is hard."
