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.
There is no team stronger than India in the Asia Cup, especially with Pakistan's current performance, it is doubtful whether they will be able to survive as India's opponents in the Asia Cup. Between Sri Lanka and Bangladesh, Bangladesh can be considered as Sri Lanka's equal, but both teams are strong in fifty-fifty matches, but either Sri Lanka or Pakistan are the teams capable of facing India in the final. Afghanistan is currently a team rich in all-rounders, so I don't see Afghanistan's potential in that way. Most of Afghanistan's players are off-form at the moment. However, India is 100% sure to be the champion of the Asia Cup and there is a possibility of Sri Lanka being the runner-up.
