Just before the hour mark Philadelphia had another great chance as Amobi Okugo was able to get on the end of a cross and hit a diving header that went over the bar.
With eight minutes to play the advantage was firmly Philadelphia’s as Kofi Sarkodie was shown a second yellow after not taking a throw-in instantly which the referee deemed time wasting.
