"England were well-prepared while India were over confident. The Indian preparation for this important series was diabolical," former captain Vengsarkar told PTI today after the visitors beat the hosts by seven wickets in the third and penultimate Test at the Eden Gardens in Kolkata.
"I hope the selectors show vision and courage of conviction. At least a couple of changes are expected straightaway," he added.
Vengsarkar pointed out that while England played three practice games in the run-up to the series to get acclimatised to the conditions, the Indian board did not field the Board President's XI in any of the games.
"When we went to England we played one warm-up game before plunging into the Test series. The same happened when we went to Australia. In contrast, England's preparations were very good," the 116-Test veteran insisted.
Concurring with Vengsarkar's views, another ex-captain Ajit Wadekar said that the Indians were complacent in their approach to the series.
"Indians' body language showed they were complacent while England had come well-prepared. They spent time in Dubai and Sri Lanka before coming here and were determined to do well. Our middle order failed miserably and their spinners, Monty Panesar and Graeme Swann bowled much better than ours.
"(Ravichandran) Ashwin seems to be a better batsman than a bowler and could be promoted up the batting order," Wadekar quipped, more in jest.
