I still find 60+ million a lot for Zubimendi, we are talking about way too much for a player that doesn't deserve that much money. But Real Sociedad knows that they are in it for the long term and need the money and Arsenal can afford it, whereas the situation, Arsenal is in is a tricky one because for three years they have been a second place team and the whole "always the bridesmaid never the bride" thing is getting a mockery from the fans not only from other teams but starting to be from their own fans too.
This is why they are not afraid of spending a bit more than they should, because they want to be the first place. Gyokeres was a situation that took too long and Sporting made a mistake, that has to be the most careful place.
If this was Pep Guardiola and Manchester City getting such a player, you won't be on here dishing stuffs like this. Before the introduction of Zubimendi, Arsenal been doing super good, I mean they've been a beautiful team when you watch them, now adding Zubimendi who can both attack and defend while linking both the defense and midfield is a big boost for the club and Arteta. They get a proven goalscoring player and they'll be able to win the Premier League Competition.
