I agree that Erik Ten Hag is now better than Xavi Hernandez, he is also a coach who has more experience compared to the Barcelona coach now. We will see how they prove on the field, because this is their first meeting because as far as I can remember these two people have never met before as coaches. Manchester United vs Barcelona is one of the big matches that will be played early.
On what basis do you say Ten Hag is better than Xavi? Ten Hag is not the only one that did very well in his former team, Xavi's team before Barcelona did really well too. He won every available trophy during his time there except the club world cup if I'm not mistaken. And currently, to me I think Xavi's Barcelona is doing better than Ten Hag's Manchester United. We can see how both teams have improved under their current Managers so you cant say Ten Hag is a better coach than Xavi.
Except you do not watch Barcelona matches. Too many injuries and poor officiating are major reasons for their early exit from the champions league.
Xavi is a smart manager. the situation of the two coaches when handling their teams is different. Xavi made quick improvements with a Barca squad that was abysmal under the previous coach. he made changes to training patterns that many of his players didn't like. not to mention the financial difficulties that hit Barca. I think that if Ten Hag had accepted the offer to coach the Barça team at that time, he would most likely have turned it down. a team that is in disarray. very different from MU who suddenly bought quite expensive players. not just one, but several that MU did.
so we can judge, who is good.
