West Ham United boss Alan Curbishley was disappointed with Sunderland chairman Niall Quinn's criticisms over their summer spending.

Curbishley, after watching his side win 3-1 at Southend on Saturday, said: "I think Niall was a bit naive.

"When you come into the Premiership it is a different ball game altogether, especially for newly-promoted sides. It is very difficult to go about your business.

"We have not spent big sums. I have spent £22.5million in this window and brought in £21m.

"We have not been inflating the market or been over the top. We are quite happy with what we've done."
