Brown told the Manchester Evening News, "It's not Chadwick we want, it's Van Nistelrooy!
"I have seen Luke Chadwick in action twice in recent weeks.
"I did watch Manchester United Reserves in action against Liverpool Reserves, and also against Leeds Reserves - but people have been putting two and two together and getting five.
"We are okay - unless Sir Alex Ferguson was to let £19 million striker Ruud van Nistelrooy become available, at our price - then we'd be interested!"
