Well, just check his scores in the recent warm-up match. They aren't great.
Like I said earlier I dropped Manzoor for Yousuf, because I was suspecting that Manzoor wouldn't score that much. And after reading that Muralitharan wouldn't play, I included Yousuf. I switched Akmal for Sangakkara and Herath for Aamer. Two of the three changes worked for me. Sangakkara isn't even playing as wicketkeeper now.
But whether I have Yousuf or not, I won't be in the top 3, because my captain Mendis didn't take any wicket so far.
