England will be “blown away” in next month’s Test series in India if they do not improve with the bat, says former captain Michael Vaughan.
England claimed a tense 22-run victory on the final morning of the first Test in Bangladesh on Monday.
They meet India, the world’s top-ranked side, in a five-Test series starting on 9 November.
“If they perform like they did against Bangladesh, it’ll be 5-0,” Vaughan told BBC Radio 5 live.
Two wickets in three balls from Ben Stokes on the fifth morning in Chittagong denied Bangladesh what would have been only their eighth win in 94 Tests – and their first against England.
England made 293 and 240 against a Bangladesh team ranked ninth in the world, collapsing to 21-3 in the first innings and 28-3 in the second.
The India side is set to feature off-spinner Ravichandran Ashwin, the world’s number one Test bowler, and slow left-armer Ravindra Jadeja, who is ranked seventh.
Vaughan, who captained England in 51 of his 82 Tests between 1999 and 2008, said of England’s top-order problems: “It doesn’t matter who goes first.
“England for such a long time are always 30 or 40 for three. If they’re 30 or 40 for three against India they’ll get blown away.
“Yes, you celebrate a win, but hopefully England, in the background, are being honest with themselves that they can play better.”
