Though nothing has been stated by the club and Tony may well have some more information on this, but we've still not got a manager for the reserve team this year. McClair is only in charge until we found someone else.
Rene's resignation, and return to Manchester has sparked the rumour mill and will continue to do so till a official announcement has been made. For me though it wouldn't suprise me to see him return. In a similar fashion to Carlos, Fergie and the players have great respect for Rene, and if he wants his old job back I'm sure that Fergie would be more than happy to take him back.
