The Kiwi has already played alongside the Pakistan man in the Caribbean Premier League (CPL) earlier this year.
The rising teen sensation from Pakistan is set to make his debut for the Heat on Wednesday’s tournament opener against the Melbourne Stars at the Gabba.
McCullum was speaking to the press after signing a two-year contract extension with the Brisbane based team.
“I’m very excited about Shadab. I played with him (in the CPL) and followed his career around the globe.
‘‘He’s only a young man but he’s already made a big impact on world cricket. He is a multi-skilled cricketer. He is dynamic in the field and has been brilliant with the bat in hand.
“I’m sure the Brisbane public will warm to him,” the former Blackcaps man said.
The 19-year-old for his part was delighted to be a part of the Australian T20 competition for the coming season and recognized the fact that he will not get much assistance in the pitches on offer.
“Last year I saw the Big Bash on the TV and now I’m playing,” he said.
“I’ll play the first three games and I want to be the best bowler in those games. I’ve seen on TV that Australia doesn’t spin too much so I’ll do my best to bowl variations to contain runs and take wickets,” he added.
The leg-spinner has risen to prominence this year after his introduction at the international stage with some promising displays in limited-overs cricket. He was an integral part of the ICC Champions Trophy winning Pakistan side earlier this summer.
Australia regained the urn after an innings-and-41-run victory over England in the third Test at Perth, moving into an unassailable 3-0 lead in the five-match series.
England will now seek to avoid a third series whitewash in Australia in their past four trips and Ashes 2005 winning captain Vaughan has called on the tourists to leave Moeen out of their plans for the Boxing Day Test at Melbourne.
The all-rounder has taken just three wickets – although he has been hampered by a finger injury – and has also flattered to deceive with the bat, with 116 runs at an average of 19.33.
He is below Australia’s number nine Pat Cummins in the run-charts while he has been dismissed in five of his six innings by opposite number Nathan Lyon, who has been one of Australia’s pivotal performers so far.
Vaughan said on BT Sport 1: “You’ve got to make the change. If Moeen Ali’s going to be the batsman that just bowls a little bit then he’s got to bat a bit better than we’ve seen already.
“For me, Moeen Ali can’t play in Melbourne.”
Former England batsman Geoffrey Boycott bemoaned the gulf in class between Moeen and Lyon.
The pundit said: “It’s not a contest. My mum could play Moeen.
“We play a batsman who can bowl a bit. He’s done quite well for us, Moeen Ali, but he’s not a quality spinner. He’s nothing like a quality spinner.”
Boycott, who featured in 108 Tests between 1964 and 1982, also highlighted the lack of credible genuine fast bowlers that could rival Mitchell Starc or Cummins for pace.
He added: “They need to get better players and they haven’t got better players in English cricket. English cricket has a paucity of quality.
“Every member or supporter of their county club will tell you somebody who they would have picked instead of one or two in this team, but you can’t honestly say at home there are players who ought to be in this side.”
With a series defeat now confirmed, Vaughan believes captain Joe Root needs to start thinking of the long-term for the Tests in Melbourne and Sydney.
He added: “Joe Root needs to take out 10 players out with him that are desperate to be out there in in the middle at the MCG.
“He’s 10 games into his role. He’s got to start having a look around the dressing room and try and identify the characters that he wants to take forward, there might be one or two that he doesn’t.
“Over the next few weeks he’s got to try to have a look around the team.
“Is it now time to start building? Is it now time to start looking at the future? And if it means that he has to make a tough call or two then he’s going to have make that.”
Cricket’s latest avatar was on display at the Sharjah Cricket Stadium in the last few days as the inaugural T10 League got underway.
The revolutionary 10-over format saw a host of international stars, past and present, battle it out for supremacy in the four-day tournament.
The 39-year-old was delighted to return to Sharjah, a ground which holds many special memories to the Delhi man.
“It’s a good atmosphere at Sharjah and I have good memories of this ground when Sachin Tendulkar scored his two hundreds in the tournaments for India so it always good to come back here and play some games,” Sehwag said at the culmination of the tournament.
The World Cup winner was full of praise for the latest format and believes that it could be the perfect vehicle for the ICC to take cricket back into the Olympics.
“I think T10 is a way forward. If the ICC wants to take cricket to the Olympics I think this is the format for that since it finishes in 90 minutes. I played two games and enjoyed that experience,” Sehwag explained.
It was a bittersweet experience for the former India man who returned to the cricket field after a long time. Competing in a fast-paced format took its physical toll on Sehwag.
“It was a little tough since I have pains in my body and those came back. My back got stiff and sore and I got a spasm because I have not been playing but it is good to be back on the field,” the Maratha Arabians skipper bemoaned.
Though he is the sole Indian to have participated in the inaugural edition, Sehwag believes more retired cricketers from the country could join the league in the years to come.
“You never know. There are a lot of players who will retire in the coming years who can come here and play in the T10 League,” he stated.
Being an IPL mentor, Sehwag believes that fresh talent from the T10 League could make their mark in India’s premier T20 competition.
“The young players from UAE and the Afghanistan are playing in this league and as a mentor of the IPL I watch a lot of players and you never know when these players come in the IPL auction. You know the players (here) have a capability to score runs and take wickets,” he explained.
When asked whether T10 could impact ODI cricket, Sehwag was emphatic in his response.
“No I do not think so. I don’t think T20 cricket affected the 50-over game and neither will T10 cricket because they are different formats and have different crowds.
“You cannot play T10 cricket everywhere in the world since this is the first league but in coming years you never know.”
