Unused subs : Tattum , O'Brien , Bullock , Fernandes . Under the Upton Park lights , the hosts took the lead inside just 11 minutes . A Djair Parfitt-Williams cross came in from the right and full back Potts was the surprise recipient , popping up to head past Angus Gunn at the far post . City rallied and Potts proved his worth at the other end , clearing Jorge Intima 's strike off the line following a corner . The visitors were in the ascendency going into half-time but within nine minutes of the restart West Ham had doubled their lead and this time it was a gift . Jordan Brown fired in a teasing cross and Drury could only stab into his own net in an attempt to clear . Olivier Ntcham , pictured playing against Roma earlier this season , pulled one back but it was in vain . City finally pulled one back with 14 minutes to go when Ntcham rounded goalkeeper Raphael Spiegel to half the deficit . Tom Holland and Jose Pozo both went close to levelling matters and substitute Fernandes shot wide when he maybe should have scored . But the Hammers held on for three points as City 's title hopes at Under 21 level took a hit .
