Rehan Ahmed described his five-wicket haul as a "dream come true" after the teenage debutant put England on the brink of a historic Test series whitewash in Pakistan on Monday.

Ahmed claimed two wickets on day one of the tour's third and final Test, but that was nothing compared with what was to come as the 18-year-old spinner tore through Pakistan on day three.

His match figures of 7-137 are the best of any England debutant since Peter Such's 8-145 against Australia in 1993, and have put Pakistan on the brink of suffering their first home Test series whitewash.

Having previously described Saturday as the best day of his life, Ahmed told BBC Test Match Special that Monday's display had left him reconsidering that assessment.

"It's probably the best day of my life again! To get five on my debut is a dream come true. It's great," Ahmed said.

"I was thinking about the five-for. I'd be lying if I said I didn't. But at the same time, I was trying to forget it. The more you try and chase the wicket, it just won't happen."

The highlight of Ahmed's performance came when his delivery had Pakistan skipper Babar Azam caught by Ollie Pope, just as the hosts appeared to have steadied the ship following Jack Leach's early three-wicket haul.

"I've bowled better balls and got wickets so just to get Babar Azam out is a dream come true," Ahmed said. "He's a very good player. Pope has got good hands so it's good the ball went to him.

"I liked [Mohammad] Rizwan's wicket because I've been working on my leg spin for the last two years. To get one to spin on the other side was great."

Meanwhile, Pakistan batsman Azhar Ali saw his final Test innings end in disappointing fashion as he was bowled for a four-ball duck by Leach in his final outing before retirement.

Azhar struggled to hide his frustration when speaking to Sky Sports afterwards, saying: "You want to finish on a high and win your last game, you want to contribute. Unfortunately, it wasn't to be.

"It was a bit of a disappointment, so I have mixed feelings. I am thankful to the England and Pakistan team for giving me a send-off.

"I was more emotional in the first innings than the second. It was a nervy start in the first innings. I was quite calm in the second but I am a human being so there was some emotion.

"I played down the wrong line and Leachy got me out. He has bowled really well in this series. It was my time to say goodbye to international cricket."
