Mourinho regrets bust ups with arsenal boss wenger

I think there may be some confusion here. José Mourinho and Arsène Wenger were indeed known for their intense rivalry and occasional disagreements during their time in the Premier League, but I'm not aware of any specific instance where Mourinho has publicly expressed regret over a "bust-up" with Wenger.

Mourinho and Wenger had a long-standing feud that dated back to their time in the Premier League, with Mourinho often criticizing Wenger's tactics and Wenger accusing Mourinho of being overly aggressive and disrespectful. However, both managers have since retired from their roles in the Premier League, with Wenger leaving Arsenal in 2018 and Mourinho being sacked by Manchester United in 2018.

It's possible that you may be thinking of a specific incident or quote from one of their many post-match interviews or press conferences, but without more context, it's difficult to pinpoint a specific instance where Mourinho has expressed regret over a "bust-up" with Wenger. If you have any more information or clarification, I'd be happy to try and help further!
