T-20 is unpredictable so anything is possible and we shouldn't forget they are literally playing a warm up trilateral series, it's a big plus.
T20 is unpredictable indeed, but India winning the upcoming Asia Cup is very, very predictable which is why I am not really interested in it though I will still check the results here and there just for the heck of it.
Am actually a bit more interested in the Afghanistan matches since they are a completely unpredictable team in literally every format these days.
Don't forget sri lanka, they are heavyweight in Asia Cup despite their standing in world cricket, for some reason they bring their A game in this tournament.
Afghanistan is good but they lack the killer instinct in crucial moment. At times, batting is also questionable. One could hope for good contest, given results are not overly dependent on toss.
