"It is challenging with T20Is. Apart from the World T20, there really isn't that much riding on the series apart from national pride and wanting to win for your country," said Watson at the pre-match press conference today.
"There is no rankings or big sort of things around and its pure entertainment value, and it certainly provides a lot of entertainment.
Watson said it would be a difficult task to get the right combination ahead of the World T20.
"There isn't much continuity with the T20 group until it gets into the WorldT20 and it makes it very challenging to get the combination right. To know the roles of different guys and how they fit in and makes it very challenging, that's one of the major reasons why we have been so inconsistent."

On his feelings about being a part of the IPL players' auction for the first time since the inaugural year, after his previous franchise Rajasthan Royals were banished from the league for two years on charges of corruption, Watson said he was looking forward to it.
"Players will now go in different directions, so to be able to get that quality team back again will certainly take a lot of time. In the end, it is just about T20 cricket now and IPL is a great tournament, and it is the first time I have been in the auction since the first year. So in the end I will be happy to go wherever, because it is always a great experience and I am looking forward to it," he said.
