Yeah we probably do need another midfield, but not to replace Scholes (wait and see how he gets on). We've got Ole back who is more than capable of playing in midfeld, plus Rooney could play there, with Van and Saha up front. Another possibility is young Rossi, stick him in Scholes' position, or indeed recall Dave Jones from loan (if possible).
I hope Scholes isn't as serious as some seem to think, although it does seem to have got experts baffled a bit.
