The prestige of the two coaches will be at stake in this match, Ten Hag and Xavi have both succeeded in making their teams better by achieving positive results in their respective leagues.
Xavi can not compare to Ten Hag who has a longer career than Xavi. Ten Hag not only has a longer career but also more successful one. He succeeded in Netherlands with Ajax Amstersdam in Eredivisie league and in Champions League with a generation of De Ligt, De Jong, Ziyech. Xavi only has one title with Barcelona recent days in Spanish Super Cub. He failed with Barcelona in Champions League this season and comparing their records, Xavi has a less impressive record than Ten Hag.
The match between Barcelona and Manchester United not only shows who is the best between the two, Manchester United also wants to take revenge on Barcelona for the painful defeats in the two Champions League finals in the 2009 and 2011 seasons.
Both teams will try to reduce their best squad by installing different strategies, the coach will try to find loopholes to weaken his opponent. It is difficult to predict the outcome of this match, because both teams have always performed well in the last few matches in the Domestic league.
Past defeats were painful for Manchester United and an outstanding form recent weeks gives them more hope that they can change their facing record against Barcelona this time. I could be wrong but I feel Barcelona have a better team and they are more stable than Manchester United so if they won't suddenly play to bad, they will be a winner when playing against Manchester United.
