 He is infamous for an incident during the 2000–01 season where during a game against Arsenal a fan came on the pitch and offered him his own royal blue Everton shirt, signalling that Nyarko was not good enough to wear the colours of Everton.After the fan was escorted away by police, Nyarko requested to be substituted and transferred.Eventually, he went on loan to French club AS Monaco just days later for the rest of the season, and then had a loan spell at Paris Saint-Germain for the entire 2002–03 season.
