Quite a lot of articles around about Vela, Sociedad, Griezman, Agirretxe, Inigo, and almost all of the others. That article hits the nail on the head though, they are a mix of the best parts of Barca and Real, and just a joy to watch. Real have for two years gone through games winning by a small or bigger margin, but being utterly horrible to watch with some dire dire football. Barca are getting ever more boring, Sociedad are a team that can pass as slickly as anyone in the world, but also counter attack like Real, at break neck speed, but often involving more players and more good passing rather than a simple knock it long for one guy to run in behind.
They are just ridiculously fun to watch because they play varied, interesting, attacking football. Go to Barca or Real and sit with 10 behind the ball, **** off, go there and scare the bejesus out of both teams with all out attack that is both effective and insanely good to watch, hell yeah.
I'm sure if you google around you can find some highlights which show the goals, they just score great goals, have great counter attacks, and do some fantastic passing.
Vela was their best player, he got a slight knock and hasn't been as good, hasn't scored in a while and only a couple assists, lately Griezman and Agirretxe have been better, but only just, they are all just fantastic to watch.
40mil euro budget vs Real's 500mil euro budget, and they had them on the brink, they did beat Barca, they scored 6 goals against Real and Barca in two games, they scored 9 against Valencia, only team to take points(or the first at least) at Athletico in like a year, because they went there and attacked. Easily the best team to watch in Spain right now, easily, by a mile, the fact that they are an underdog, ridiculous budget and the rest just make them so much more loveable.
The only slight issue is, euro football, small, infact TINY squad + no money, the extra games can often badly hurt a team in the league. I really hope they get it though and don't dive down the table next year.
