In Test cricket, Pakistan is obviously not one of the best teams because Obviously, they are sixth in the standings. and it is not just good enough to say that they are one of the best.
if there were a lot more teams playing like 50 or 60 and among them Pakistan was sixth, then it would have been ok to say that they are one of the top teams,
but there are only 10 teams playing regularly and being the six amongst them is not good enough to be a top team.
In last one decade Pakistan suffers badly due to terrorism issues and unable to play at home which hurts them very badly otherwise Pakistan is still top ranked team in test history with their overall percentage now after successful tour of Australia we can say they will do some better and take higher rank in ICC test ranking which could be third or fourth is surely in near future which could be increased after some good number of matches.
But, if someone says Pakistan is not good test side it's his own view without checking all details about test history and their record because Pakistan is fourth-best test playing cricket side in test history.
Recently we have some good decline in test matches which is surely hurting few countries because ICC is never been a good sports authority which can handle this all fairly, so it's beneficial for few countries so if they manage for all then surely we can expect some good results from other countries as well.
I agree that Pakistan was one of the best test-playing nations in the whole world. But, I think people need to realize that they were the best team in the world and it's in the past.
There was a time when Pakistani fast bowlers absolutely terrorized the opponent's batting lineup. and it was really great to see from a neutral point of view also.
But, in recent times Pakistan has not been up to the mark because of a lot of political and situational reasons. and to be honest I really don't think Pakistan is that bad. I just think that Pakistan really needs to have a little more confidence in themselves.
