Marcus Tavernier and Isaiah Jones are two players that have already attracted interest from the higher division, with the pair certainly possessing the ability to play Premier League football.
Tavernier has been subject to strong interest from Bournemouth, with a Football Insider report claiming that the Cherries are readying a £10 million bid for the attacking midfielder.
Jones, who thrived in a right-wing-back role last season is currently being monitored by Chelsea, Manchester United and Tottenham Hotspur during the early stages of this transfer window, as per a report from 90min.com.
