Seems to me a fairly easy choice to choose United, much more potential in that team. They just won't play CL next season.
To be honest, i personally do not see any potential in Manchester United, yeah i know that they have a new manager and there is so much hype surrounding him (Erik) at the moment, but who is sure he is going to turn out successful, remember that managers like Mourinho have come and gone, yet no visible improvement. United obviously can't win the league next season, or anytime soon for that matter, they are also not in the CL, and who is sure when next they will play in the CL, so where's the potential.
^Agree with this. Lot of managers have come and gone but none of them had success like Ferguson did. They need a manager with team building history and and ten Haag is the one who has built Ajax strong over the couple of years. They are just trying managers and honestly no manager would guarantee building back team strong in less time. All of them would take time and the management needs to understand that. I hope ten Haag changes things for good at United.
