It all depends on the top 4. One of Imam and Babar have to bat through til the end and the rest need to score quickly.
If Pakistan end up 150-5 and it's Shadab and Faheem at the crease with nothing to come, then they will lose even against this England side.
Pakistan's lower order is going to be very vulnerable in this series as there is no batting all rounder among the bunch. The top order cannot afford to fail.
