WI are not a trash team, they have some very promising youngsters like Roston Chase, Shai Hope, Alzarri Joseph and Shimron Hetmyer.
Dominica Test wouldn't have been as close as it transpired if Hasan Ali hadn't dropped Chase twice, Abbas overstepping on a wicket and a poor umpiring decision. Shannon Gabriel was clearly out from an edge an hour before he eventually was bowled by Yasir, but umpires bungled the decision..
We beat WI comfortably in UAE in Dubai and Abu Dhabi. WI were never going to chase 350+ in that day night Test so it wasn't as close as you're making out. As for Waqar never being whitewashed - that's because he never stepped out of his UAE comfort zone - he would've received the same beatings on these tough tours believe me.
Anyway these are the FACTS:
2011 - West Indies 1-1 Pakistan under Waqar.
2017 - West Indies 1-2 Pakistan under Arthur. Deal with it
