meaning in context - 'Team' doesn't or don't'?

I have found that in BrE, 'the team' is either singular or plural, while in AmE, it is always singular from here: Team as singular or plural

I read the following line in the article:

Given the right conditions, and the team playing to its potential, Kohli will be disappointed if his team don’t win the series.

Now, my question is: Should we put 'doesn't' in place of 'don't' as looking at the context, here 'team' looks singular? Why?
