Andrew Strauss has backed Kevin Pietersen and Alastair Cook to prove their worth to England in this week's second npower Test against Pakistan at Edgbaston.
Pietersen goes into the match on a run of 22 Test innings without a century, passing 50 only five times in that period, and will be desperate for runs as England seek to build on their impressive 354-run win in the first Test at Trent Bridge last week.
But captain Strauss said: "He's been really good this week, he feels like he wants to get that score but we're very happy with what he's doing and he will come right."
He added: "You always want to get that score on the board and prove you're as good a player as everybody thinks you are.
"We all go through it, you're not human if you don't go through a poor run of form at some time, but players of the quality of KP always come back and he will."
Cook has made only 79 runs in five innings since his 109 not out against Bangladesh in Dhaka but Strauss is adamant it is too soon to put pressure on his opening partner.
"It was only a few Tests ago that he was getting a hundred against Bangladesh," he pointed out.
"You can get too focused on a couple of bad innings, Cookie has made some good adjustments."
