In my opinion Dav Whatmore, the current Bangladesh Coach, must rank as one of the best coaches in International cricket today. He previously coached Sri Lanka and helped them win the World Cup. He was also responsible for selecting and coaching some of their current cricketers and raising their standard in Test Cricket. The recent performances of Bangladesh in West Indies and their performances against England, suggest that he may have done it again, in making them perform far higher than what they did before him.(as he did with the Lankans). The small pool of talent, lack of resources, the lack of formal coaching of some of their cricketers and the poor quality of First Class Cricket in these two countries makes his achievement all the more commendable.
Some would argue that Duncan Fletcher should be considered as the best current International Coach. But the large pool of talented cricketers that are available and the resources that are available make the comparison with Dav Whatmore very lop-sided.
John Wright would come close in this comparison, in considering the high achievements of India in the past year. But again he has a very skilled bunch of cricketers to work with and refining their technique and thinking may have been his forte.
While John Buchanan is a great coach, the highly talented pool of cricketers he has to coach, makes the comparison difficult.
What do others think? I personally think Dav Whatmore deserves a lot of credit for the improved performances of the two Teams he has been associated with. He could arguably be regarded as the best Current International Coach.
