Green and Parker could be about to play one of their last games for West Ham as both will want to play Premier League football this coming season.
All four players at some point could share the same pitch in the Championship tomorrow and it's an indication that West Ham should be too strong for City.
Also in the West Ham line up is Carlton Cole, the striker was close to a move to Stoke this summer but his £40k a week wages were a stumbling block.
West Ham have just signed John Carew, his move was completed on Saturday but too late to face Cardiff on Sunday.
