The Europa League means a lot right now for Barcelona fans, I was on Facebook some time ago and there were some memes indicating that they were going to the Europa League, and I know there were other memes where they said they didn't want to return to the Europa League, but here there are several questions, is this Xavi's fault? because very strong games will come, just see Man United (without CR7) who could win? partly if they don't play with CR7 because of the multiple problems they would be very disarmed, and if they put in Maguire it would be a total disaster, then we could say that Barcelona could breathe a little more.
Coming back from world cup straight into europa would have been hard, it's good that we are not going to have it back to back, teams should rest a bit and do just league games for a few weeks before they play serious games. That way everyone would rest a bit, and then they can get back to being the way they are and it would help them a ton.
I personally would love to see it go on even later on, like not even afterwards but more like April or so, and just condense the games quicker, once every week, that would be a lot quicker results and would help the fun be a lot better as well. Because that way we would get both better players that are rested, but also more games for a good 2 months.
Yes, in this order of ideas, as you put it, it can be positive, obviously when you return from a World Cup, the players are very tired and the fact of having a rest in December helps them to recover a lot for their games, I think some they will return with the firm position of winning in their pending games, some will transfer to other teams and others will arrive new ones, this Europa League will be very exciting and I like that, after having a good dose of football in the World Cup, there is nothing Better than being in a rather voluptuous UCL and Europa League, there are many changes in many clubs, and some are in trouble like Juve, Man United.
