'Unacceptable' collapse has lifted England - Waqar

Waqar Younis, the Pakistan coach, has called the team's second-innings batting in Abu Dhabi "unacceptable" after they were left grateful for the arrival of dusk to prevent defeat in a Test where the final day had begun with the first innings incomplete.

England declared with a lead of 75 and Pakistan were rocked early by James Anderson, who struck twice in an over, followed by the run out of Mohammad Hafeez. A stand of 66 between Younis Khan and Misbah-ul-Haq had appeared to calm the nerves and confirm the draw, only for Younis to spoon Adil Rashid into the covers and Misbah to charge down the pitch at Moeen Ali and miss his expansive shot.

"It's unacceptable to bat like we did in the second innings," Waqar said. "It should have been a straightforward draw but we allowed them to threaten us and beat us. We allowed them to come that close, we allowed them to threaten us and run away with the game. We should realise that we are a very good Test side but we committed some silly mistakes, especially in the batting which could have cost us the game."

"The way they played, we have to really pull our socks in the second Test. What happened was not on and we have to really improve on that if we want to win the series. We have experience in our batting, we know our batting and know it should have lasted the final day, or the final session but we didn't and that we have to consider.

"I am confident that my side can bounce back but we have to realise that it is all about playing all sessions equally well and if you don't in one session the opponents come down hard on you as England did."

Waqar knows that Pakistan will be boosted by the return of legspinner Yasir Shah, who missed the opening Test after suffering a back spasm the day before the game, but said that they cannot afford to purely rest on the comeback of their star bowler, even suggesting the favourites tag has shifted in the series.

"Fair enough we will get Yasir back but they will be thinking that they can compete. Before the series started it was their own verdict that they were underdogs but now we are the side which have to stage a comeback."

Yasir's return, at the expense of either Rahat Ali or Imran Khan, will also be welcomed by England according to their coach Trevor Bayliss who said the "ego" of international cricketers meant they wanted to be tested by the best players.

"The boys want to be the best team in the world and that means you have got to play the best players and he is the best player," Bayliss said. "I'm sure these guys would like to test themselves against any of the best players and come out on top.

"At this level the egos are right up there, they want to play the best and show the best that they are better than them. They will want to show him they can play him as well as any other these other players."

The lack of specialist spin cover in the original squad to cover for a circumstance like Yasir's injury has angered Misbah and could lead to more back-up being available this time. Bilal Asif, the offspinner whose action is currently being tested, has been added to the squad for the second Test.
