Sammy made it very clear before the series started that they wont take BD lightly and they are looking to win the series. It can be said that WI were focused for this series. So how can you assume that "YOUR PLAYERS TOOK BANGLADESH LIGHTLY?". Your team struggled against spin and you dont have a solid batsmen in your lineup that can ensure that you guys can make big runs in ODIs. Yes i agree WI are a much more settled team when it comes to tests and T20s but frankly you guys dont have wat it takes when it comes to ODIs. Your very lucky to have Kemar Roach who rattled our batting lineup in the 4th ODI or else it would have been an easy ODI series win for Bangladesh.
Your team was simply not good enough in this ODI series. Just face the facts.
