Vassell, 28, was robbed of his designer watch and jewellery on his return home from the club's Christmas party.
Vassell was not injured during the incident, but was threatened by the two offenders.
It is understood the attackers had not specifically targeted the former England international, but struck while the player reportedly disputed his taxi fare.
The raid took place at the junction of Palatine Road and Barlow Moor Road in Didsbury at about 5.30am on Sunday.
It is reported that Vassell was 'relieved' of almost £23,000 of bling, and giving where the incident occurred, it sounds like some 'quality' time at Friday's could have been on the agenda.
