Former England Test captain Kevin Pietersen does not want to see Ben Stokes made skipper should Joe Root miss a game against West Indies next month.
England are set to return to action with three behind-closed-doors Tests against the Windies at the Rose Bowl and Old Trafford.
However, current five-day captain Root may be missing for one of those fixtures as his wife, Carrie, is due to give birth, with the batsman conceding he would leave the bio-secure areas in Southampton and Manchester to attend the birth.
Root has not missed a Test since being named captain in 2017 but has backed current vice-captain Stokes to step up should he not be available.
However, Pietersen has advised against having all-rounder Stokes fill the void given his own brief experience of a role he had for only three Tests.
"Do I want to see Ben Stokes change from who he is and the current player he is? Probably not, Jos Buttler would be my guy," Pietersen, who resigned as England captain in 2009, told talkSPORT.
"The entertainers and the guys that have to carry the mantle in the team sometimes aren't the best captains and sometimes struggle with the extra added pressure.
"As a player you are looked at completely differently until that phone call comes and you are announced as the Test captain.
"Responsibilities change, communication changes, the way in which you carry yourself in the dressing room changes.
"I struggled with it, I absolutely hated it and I was rubbish. You have to change and I couldn't command the respect of the dressing room. You say something and it is frowned upon, it is a completely different story."
