Yeah, Quetta Gladiators have won their last 5 matches. The team is in great form. But we don't know how the team will play after the break. Moreover, Islamabad United won the last match against Karachi Kings. You might be thinking that Karachi team was unbeaten in their last three matches. Even then, Islamabad United won this match by a huge margin of 79 runs. Islamabad is back on track. But if they cannot continue this performance, they will not be able to win. But since the performance of Pakistani players is very erratic, it is difficult to make predictions about PSL matches.
Both Islamabad United and Quetta Gladiators are strong teams and that is the reason why they are playing in Qualifier 1. It seems like Colin Munro may not be playing for the United, and that will be a big handicap for them. On the other hand, Gladiators have most of the star players available, including Hasan Nawaz, Faheem Ashraf, Abrar Ahmed and Saud Shakeel. But the most important factor that we should remember is that United has lost all of their recent matches, except the one against Kings.
