The uncapped Sibley will be one of the few names up for discussion as England decide their Test squad for the two-match series against New Zealand in November-December.

“He is a mature guy, who works extremely hard and is really ambitious, so it’s difficult to look past what he’s got this season,” Giles, ECB’s managing director for men’s cricket, said.

“Dominic is not the prettiest on the eye all the time, but then neither is Rory Burns or Steve Smith. He is a mature guy, who works extremely hard and is really ambitious, so it’s difficult to look past what he’s got this season.

“Whatever your technique, if you are batting that many balls, you are doing something right, so I’m delighted for him, having taken him to Warwickshire. But his selection will come down to Ed Smith and James Taylor.

“You have to go for the players who can deal with the stresses of Test cricket because that is as important as anything.

“We have some good young players in the country, but are we playing in the right conditions which will help them fully? You could argue probably not.”
