'Drop Sinckler', says Brian Moore as he picks his England front-row for the Six Nations

Moore said: "In the front row Joe Marler and Ellis Genge are both on form and Mako Vunipola at loosehead makes a trio as good as any other country in world rugby."

Moore said: "Luke Cowan-Dickie and Jamie George cover hooker more than adequately, but it is at tighthead that Jones could have problems."

Moore said: "Kyle Sinckler has struggled along with the rest of his Bristol team this year, and after him, the choices narrow considerably. If you had to take current form, Tigers’ Dan Cole would be due a call back to the squad as his form is better than it has been for several years.

"However, you cannot tell whether Cole really wants to return and it could be that he has settled back in at Welford Road and is content to be playing in front of the Leicester faithful.

"In terms of scrummaging, a name you might not be familiar with could come into contention: Will Collier of Harlequins. His scrummaging has helped Quins’ front row become a destructive force once more.

"His work rate is excellent and he has recently taken to scoring tries. Unless Jones wants to risk playing someone such as Marler on the wrong side of the scrum, Collier is his best option to shore up the starting front row."
