From all the circumstantial evidences, and the events leading upto to the murder, it seems most likely that Bob was done in by his players.
The manner in which they lost to the minnows, Ireland, shows that many of the Pak players were bought and they threw away the match.
Bob . who knew his wards inside out, made out that many of them were playing below par, for obvious reasons. He threatened to disclose this. The players, without realising the consequences, plotted his murder, and executed it, before Bob could let out the cat.
Mohd. Yusuf overreacted on Bob's death, and the way he was weeping , was most unrealistic!
The real truth is coming out very soon..lets wait!
