Former England captain Geoffrey Boycott feels England's hammering of India might leave spectators disillusioned and deepen the problems of Test cricket.
"I am thrilled and delighted by England's performances. But it is a shame that they have risen to No 1 in an era when other countries' Test teams are declining," Boycott said.
"It's not England's fault that others are failing to match their standards. But the timing is unfortunate. India's financial might is the biggest thing cricket has going for it, from a business point of view, and everyone will suffer if their spectators get disillusioned.
