Former Australian cricket firebrand David Warner has re-ignited an Ashes rivalry after footage of him appearing to charge at English star Moeen Ali in the Pakistan Super League went viral.

The incident unfolded moments after Karachi Kings pulled off a tense five-wicket win, with Warner seen gesturing angrily before moving directly toward Moeen during the post-match handshake line.

In the now-viral clip, the Australian captain appeared visibly fired up as he approached his teammate, prompting team director Haider Azhar to step in and physically guide him away as the exchange escalated.

The timing of the moment only added to the drama.

Karachi needed just five runs to win in the final over when Moeen was trapped LBW on the very first ball, briefly opening the door for a late collapse.

With pressure at its peak, Abbas Afridi ultimately sealed the victory with a first-ball six, but the tension of the situation appeared to linger as players lined up to shake hands.

Warner, who had earlier anchored the chase with a crucial half-century, looked anything but relaxed as he confronted Moeen.

Fans were quick to react, with many suggesting the moment showed cracks within the team, while others pointed to the intensity of the situation after such a dramatic finish.

The involvement of Azhar, who stepped between the pair and pulled Warner away, only heightened the sense that something serious had unfolded.

But just as quickly as the narrative exploded, it was challenged.

Warner later moved to downplay the incident, insisting there was no argument behind the scenes.

'I said to Haider Azhar to go first and shake hands,' he explained.

Despite the clarification, the footage continues to circulate widely, with many unconvinced the moment was as innocent as suggested.

And the contrast with events just days earlier has only deepened the intrigue.

Less than a week before the incident, Warner had publicly praised Moeen's performance after another Karachi Kings win, highlighting his influence with bat and ball.

'I think at the beginning we thought 170 was probably going to be par,' Warner said.

'We lost a few wickets in the middle there with a few poor stroke selections, including myself.'

'But all in all, the way that Mo played in the partnership towards the back end to get us to a good total was fantastic.'
