The shift across the English Channel would see the former Highlanders star link up with his old mate Lima Sopoaga who is having a difficult first season at Wasps.
The Times reported on Wednesday (NZT) that an official announcement on Fekitoa's move was expected "in the next few days". It would be a welcomed signing for a proud Wasps club about to lose some significant talent in the form of England test No 8 Nathan Hughes, Springboks fullback Willie le Roux, highly regarded tighthead prop Jake Cooper-Woolley, and probably England outside back Elliot Daly.
