Wasim is a strange case...well then again I guess not..like most people...these days he says that which the audience want to hear.
I think back in the 90s..when he rated Crowe and Richards..those were his real opinions and it is totally understandable as India and Pakistan did not play test cricket back then and Lara had failed in the few test matches WI played against Pakistan..Crowe on the other hand was the only one who knew how to play reverse swing..and Viv is just Viv!
These days..Crowe is obviously not as popular a player and is not talked about as much..
Wasim is mostly in India doing shows and commentary..so these days he mentions Tendulkar without blinking an eye lid..
But then I watched another segment on TV where he was in a show with Shastri about great knocks and one segment was about Lara's 400..and on that show Wasim said Lara is the best he has ever bowled to..
I have seen McGrath, Warne, Murali do the same thing..recently Murali said he had no issues against Tendulkar but I remember a couple of years back he was in India and he said Tendulkar is the one batsman he had never managed to deceive..
So I wouldn't take their answers too seriously
Most of the time they are playing to the crowd..
