The 17-year-old, who is the youngest player to have signed for a BBL franchise, has already featured in over 46 T20 fixtures, including in various leagues across the globe.

"The thing for him is since he's arrived on the international scene he's performed wherever he's gone – and he's gone everywhere," Vettori told cricket.com.au. "He's played in most competitions around the world and he's been highly successful."

"He's got so much experience in such a short period of time that I think he really understands his game. I think that's true of all the Afghan players – they all feel like they are self-coached, so, therefore they really know what they're doing in any situation."

Vettori further added that Mujeeb, who is a part of franchises like Bengal Tigers, Comilla Victorians, Kabul Zalmi and Kings XI Punjab, will extend Heat's tradition of bringing in reliable spinners to bowl in the tricky conditions at the Gabba.

"We've tried to play a game predominantly around spin at the Gabba with Mitchell Swepson, Shadab Khan, Yasir Shah and (Samuel) Badree over the years," Vettori pointed out. "I think Mujeeb will continue that on."

The teenager's ability to remain calm under pressure and his strong action are his biggest plus points, said Vettori.

"From what I've seen, he doesn't get flustered, the pressure's not an issue for him, and he just gets on with things and particularly bowling at the Gabba, that's the mentality that you need. The thing that separates him I think is his action," he added.

"He's very tall, he bowls quick, and he bowls from a height that makes it difficult. His variations, while you won't see them as much on a wicket like the Gabba, his control of those variations set him apart."
