Arthur has said Watson, who also plays in the IPL and the Champions League, will continue to be pulled out of certain matches for his country in order to ensure he is fit and hungry for big series like the Ashes.
"I came off a five-week break and I was able to really get some training under my belt but also have a bit of a mental break, to be able to hit this Twenty20 world cup running," Watson said.
"The games in Dubai were a brilliant lead-up for us, the conditions, the heat, and things have fallen my way here. In Twenty20 it's a very fine line between having a good game and having a not-so-good game, so you've got to make the most of these times."
