Don't want to go OT here but I've posted article in the Alvarez thread a few days ago that says he wouldn't be a good fit for Barca.
I read your link and it was an interesting piece. I just wonder if it ignores what Xavi currently is looking for in his 9. Someone who has good link up, can press from the front has decent pace and (obviously) ultimately scores. I think our attacking pace and focus will be brought from the two wide men creating cut backs to the CF and emerging midfielders- so we probably won't be hurt too much from Julian not being a pace merchant or elite in any single facet.
If Alvarez doesn't have the profile that the article mentioned, then neither will Fati.
Back to Jutgla. He is probably starting versus Sevilla and is going to stick with the first team over after the winter break. What a crazy ascension. Fully expect the form to drop to his real level within a handful of games, but stories like this can't help but make you feel happy in modern football.
