The former Queen’s Park and Dundee United defender is believed to have risen to the top of Sherwood’s wanted list after a series of fine displays in his first season in English football with Hull City.
With the Tigers relegated, Sherwood is planning to entice Robertson back to the top flight, but he faces competition with both Arsenal and Premier League champions Chelsea monitoring developments.
Robertson is included in Scotland boss Gordon Strachan’s squad for the double header against Qatar and the Republic of Ireland.
And with Swansea and Everton long-term admirers of the 21 year old, it looks like he will be in demand once this season finally comes to an end.
• Defender Mark Durnan looks set to be the fifth regular starter from the Queen of the South team that reached the Premiership play-offs to depart Dumfries for pastures new this summer.
The Palmerston club have already lost Dan Carmichael to Hibs, Kevin Holt to Dundee and Ian McShane to Ross County, with striker Gavin Reilly all set to sign for Hearts.
Former St Johnstone centre-back Durnan is in demand with three Premiership clubs chasing the 22 year old’s signature as Motherwell and Dundee United are keen along with his former manager Jim McIntyre at Ross County.
