Somehow, Barcelona succeeded in organizing a very strong squad. It's interesting because they did this with very little money.
What's even more interesting is the fact that they have built a better team than the likes of Chelsea, PSG, and Manchester United which all have deep pockets.
I agree with you but these results Barcelona achieved lately are from months of preparation with young skilled players. I've always said that Barcelona has been on the path to recovery and coming back under Xavi's coaching. His main focus has been to bring back Barcelona to their rightful position since many iconic players (Messi, Suarez,iniesta…) left they needed time to rebuild and adopt a new style of play.
This season right from the early of LaLiga matches it was obvious that Barcelona would compete in all leagues and achieve better results than last year. With a good combination of young talented players and Xavi's experience I believe they have a real shot this time and today’s match was their first victim only.
In today first round of the UCL, most match were as expected IMO, with teams performing similarly to their performance in their local leagues. There was only one exception with Atletico Madrid who lost two points in the last minute. A very rare surprise when Lazio goalkeeper scored the draw goal 1-1 in the 94th minute of the match. This makes him
the second goalkeeper in UCL history to score a non penalty goal and the coincidence of wearing the number 94 and scoring in the 94th minute.
