The tighthead is set to come to the end of his contract with Quins by the end of this season, but talks appear to be stalling.
Johann Ackermann’s side is in the market for a tighthead, and the capture of Sinckler would represent a major signing coup for the Cherry and Whites.
Meanwhile Harlequins are enduring a mixed start to the season under Paul Gustard, sitting ninth in the Premiership with just one win.
Sinckler has represented England at U16, U18, U19, and U20 levels before making his test debut as a replacement in England’s 37-21 win over South Africa at Twickenham on 12 Nov 2016.
After making his first nine England appearances from the bench, Sinckler made his first start against Ireland during the 2018 Six Nations.
The London born prop was picked for the British and Irish Lions squad in 2017 and won the penalty that led to Owen Farrell kicking the Lions to a 24-21 victory in the second test.
The 120kg prop however conceded the second most penalties of any player during the 2018-19 Premiership season with 29 behind Northampton’s Alex Waller. Harlequins captain Chris Robshaw spoke to him about discipline after he received a yellow card for slapping Sale’s Faf de Klerk in the chest.
He was infamously described as an ‘emotional timebomb’ by Wales coach Warren Gatland during the 2019 Six Nations. Subsequently, Sinckler conceded three penalties during England’s 21-13 defeat by Wales and was replaced in the 57th minute.
