Here, we look at at five Ladbrokes Premiership players who could spark offers this month.
The former Fulham player has not been as prolific as his 32-goal debut season for Celtic, netting eight times after missing almost two months with a hamstring injury. But a goal against Paris St Germain and a stunning hat-trick for France Under-21s boosted his profile in his native country. Brighton and Stoke have been linked with the 21-year-old, who is less than halfway through a four-year deal.
Celtic are reported to have had an initial offer rejected for the Dundee centre-back, who signed from Wigan in the summer. The 22-year-old former Partick Thistle player is thriving with regular first-team football after playing more in loan spells with Shrewsbury and MK Dons than he did for the Latics during a two-year spell.
The former Middlesbrough trainee has proved a real threat out wide for Kilmarnock and has improved his defensive game after working under Lee Clark, Lee McCulloch and now Steve Clarke. The 23-year-old winger made his Northern Ireland debut during their World Cup play-off against Switzerland.
Rangers rejected a bid from Preston for the wide player last week but North End could return with a second offer. The pacey 23-year-old has scored six goals this season and looked a far more dangerous player than during his first campaign at Ibrox.
Hearts rejected a £500,000 offer from Rangers for the wide midfielder during the summer but would lose the 24-year-old for nothing if he left in the summer. Walker, who has scored twice this term, has been linked with Wigan but missed Saturday’s draw against Aberdeen with a knee injury.
