Director of Rugby Dai Young was reportedly keen to land the 31-cap All Blacks playmaker from Toulon in 2017.
With Danny Cipriani, who eventually joined Gloucester, and Jimmy Gopperth potentially departing the Ricoh Arena that summer, Wasps were keen to get a deal for a number 10 tied up by January.
Gopperth would eventually sign a new deal with the black and golds also signing Lima Sopoaga and Billy Searle ahead of the 2018/19 season. McAllister eventually joined Clermont before retiring.
