Yasir Shah will be key - Wahab Riaz
England were rattled by Riaz and Shah on the third day, with each bowler picking four wickets as the visitors were bundled out for 242 runs.
In their second innings, Pakistan were aided by fifties from Mohammad Hafeez, Younis Khan and Misbah-ul-Haq while their lead stands tall at 358 runs at stumps on day three.
Riaz feels that Shah will be most crucial for Pakistan on the fourth day as the pitch will offer plenty of support for the spinners.
"I think Yasir Shah will be a key player tomorrow (fourth day).
“There is a lot of spin in the track right now.
“For the kind of score we are looking for, if you put that much of a target, England will be under pressure and it is not easy to play spin on here."
The 30-year-old left arm pacer also believes that Joe Root will be a key player for England and that Pakistan will have to get his wicket early.
"Obviously, Root is a very good player, a very aggressive player, so we know he us a very important person to get out.
“We thought by getting him we could dry up the runs and put pressure on the incoming batsmen.
“That is what happened.”
England began the third day with the score reading 182 for three and a fiery spell of bowling from Riaz saw the hosts being reduced to 216 for six.
Speaking about his bowling exploits on the third day, Riaz admitted that he was lucky enough to get wickets on the pitch that did not have much help for the fast bowlers.
“At times it happens where you bowl really well but don't get a wicket.
“Sometimes it happens that you can get a wicket on a bad ball.
“In cricket you always have to put effort into it.
“I think I was quite lucky to get wickets on these tracks.”
At stumps on the third day, Pakistan were placed at 222 for three with Younis and Misbah batting unbeaten on 71 and 87 respectively.
