Arsène Wenger has made no secret of his intention to sign a new defender this month but the Arsenal manager has warned that the transfer market is not like a supermarket.
A number of centre backs have been linked with a move to Emirates Stadium and although Wenger is keeping his cards close to his chest he knows that there is competition to secure the best players.
"Everybody looks for centre backs in the whole world," said the Frenchman. "People with unlimited resources look for a centre back.
"We have specialised people to work everywhere but we are not in a supermarket where you go to a shelf and you ask where are the centre backs or the strikers."
According to Wenger, there are "two markets" at work at this time of the year.
"There is a top, elite market and no market at all," he said. "The gap in football has become worse and worse.
"I don't know if you have seen in Spain but the top players go on strike because they are not paid. There are only two clubs, maybe three with Malaga, and there is no logical economy to set any price for what a player is worth.
"If a player is interesting the top clubs, he has a fantastic value. If there is no interest from these clubs he is £3-7million.
"The same player can be worth £30-50million and £3-7million. There is no logic in the market any more. In football it is very difficult to set the price for the players."Copyright 2013 The Arsenal Football Club plc.
