There have been some good points raised on Barry's valuation. For some time now, the market for English players has been severely inflated regardless of whether we agree or disagree on the valuation. We have seen much evidence, more recently with the case of Bentley and it appears that this will continue.
Despite how we feel about these prices, this changes nothing; after all, we're not talking about a stock price which may crash or even a car which depreciates in the longer term. Like it or not, these are the conditions in which the market operates and the club either accepts this, continues to purchase lesser quality players or buy foreign.
