Ollie Robinson said captain Ben Stokes and coach Brendon McCullum gave England confidence they could win under any conditions.
“The belief we have is unmatched,” said rhythm bowler Robinson.
“The belief is that we can win on any ground. We can score 1,000 runs and we can take 20 wickets.”
England’s fast run at Rawalpindi broke a host of records. The 506-4 they racked up on day one was the most in Test history and their 6.73 game rate is the fastest a two-hitter team has ever scored.
But perhaps more impressive was the creativity and persistence England showed to topple Pakistan on what Robinson called the flattest ground he had ever seen.
Robinson took four wickets in Pakistan’s second innings as he and James Anderson put on a masterful display of reverse swing bowling on the final afternoon.
It is the latest performance in a successful return to Test cricket for Robinson, 29, who has missed most of the first half of the year due to a number of fitness issues.
After his fitness was publicly criticized by former England bowling coach Jon Lewis during the Ashes in January, Robinson changed his training habits, saying he had turned into a “gym maniac”.
The result was a relentless display in Rawalpindi, for which he was named Player of the Match.
“All the hard work I have done in the last 18 months, the dark places I have been, to come here to Pakistan and take 20 wickets on this wicket is my proudest moment as a cricketer English,” Robinson said.
“I’m very proud of the job I’ve done and the quality of England’s behind-the-scenes staff to get me to this place.”
England will now look to seal their first series victory against Pakistan outside the UK for 22 years at the second Test in Multan.
Although he only has a three-day gap before the start of the game on Friday, Robinson believes he will be fit to play again.
“I’m going to take a few ice baths and a bit of physio treatment, some rubs, and hopefully be good to go,” he said.
“I want a few days off and a little practice before the second test and everything will be fine.”
