This after the former England captain said the current squad failed to respect Test cricket during their 340-run loss to the Proteas at Trent Bridge on Monday.
Vaughan, who is a close friend to the Root family after playing alongside his father Matt and also said to be the boyhood hero of Joe, slammed the current crop of English players after they lost seven wickets for 62 runs in their first innings.
Vaughn said: “Maybe it’s a lack of respect about what the game is.
“They look like they are playing a Twenty20 game. They have this approach of attack, attack, attack. There is no thought or feeling of seeing off a bowler or wearing a team down.”
England’s loss to the Proteas was their sixth defeat in their last eight Tests but Root still felt that Vaughn’s comments were uncalled for.
Root says: “I think that’s very unfair - I can’t believe he’s actually said that.
“We pride ourselves on winning series like this, and unfortunately we’ve played poorly this week.”
Root admits that his span came up short at Trent Bridge and that they will need to improve ahead of next Thursday’s Test at the Oval, adding: “We need to make sure we learn quickly.
“Part of Test cricket is trying to find a balance of both [attack and defence]. And even if it’s not your strength, you build it into your natural game.”
