The Scotland international moved to the KC Stadium from Dundee United in summer 2014, going on to register 76 appearances across all competitions for the Tigers.
That includes 42 Championship outings last season as Steve Bruce’s side obtained promotion to the Premier League through the playoffs.
However, that may well prove to be the 22-year-old’s final appearance for Hull City, amid heavy interest from Premier League rivals Liverpool.
The Reds are targeting Robertson as an alternative signing to left-back prodigy Ben Chilwell, who Leicester City are demanding £10million for despite being yet to make his Premier League debut.
And Mirror Football’s latest reports suggest Hull City are willing to do business with Liverpool – provided the Merseyside club meet their £12million valuation.
That money will likely be spent on re-signing Robbie Brady, who is expected to cost the same sum from Norwich City.
