The news source claims that Manchester United are going to be seriously interested in bringing the current PSG manager Mauricio Pochettino this summer. There have already been some rumours like PSG will part ways with him at the end of the season. And their target would probably be Zinedine Zidane. Manchester United also can go for him actually but PSG would be the winner in this rivalry I guess. Therefore, Pochettino can be one of the best options for them as he knows the Premier League very well too.

I know how Pochettino has known the EPL for a long time at Spurs but I don't think he will be able to compete in the EPL considering his strategy is still not patented, while how the EPL is so tight now and next season.
