Pakistan is in trouble in this test match.I think we will see again result of this test match as well.This time odds are in favor of English team.There will be also another interesting match between Srilanka and West Indies.I would go for that as well.
Tomorrow first session is very important for both teams if England takes 2 or 3 wickets then they will control the match otherwise we have all options alive
You are right, first session will be very important for both the teams and this session will decide who will dominate the remaining days in the match. England will look for couple of quick wickets during the start of the first session.
