Robertson, 21, started his career as a youngster with Celtic, but was released for being 'too small' - a decision which has certainly come back to haunt the Bhoys.
The defender moved on to Queen's Park, way down the Scottish football pyramid, but his performances earned him a move to Dundee United in the summer of 2013. After impressing again at Tannadice, Robertson was in the Premier League just a year later, capping off a stunning rise.
Robertson couldn't help Hull avoid relegation last season, but he's enjoyed a superb campaign in the Championship, as Steve Bruce's side push for promotion back to the top flight.
Now, the Daily Star report that some of the Premier League's biggest clubs want to sign Robertson, with Manchester United potentially looking to bring him to Old Trafford as competition for Luke Shaw next season.
The report also claims that Tottenham Hotspur - along with Arsenal and Manchester City - have been scouting Robertson, and could target him after those scouting missions.
Spurs already have two impressive left backs in Ben Davies and Danny Rose, but if one of them was to fall down with an injury or even be sold, then Robertson may figure into Mauricio Pochettino's plans as a possible replacement, especially given Tottenham's willingness to sign young players and give them regular first-team opportunities.
A pacey, attack-minded left back with great delivery into the box, the eight-cap Scotland international appears destined for big things - and if Hull miss out on promotion, the Premier League's big boys could try to tempt the Tigers into selling Robertson this summer.
Would Robertson be a good signing for Spurs or Arsenal?
