Xavi has prepared the team to bring Barcelona to compete with other big clubs from different leagues, this time the toughest competition will come from the premier league team, Manchester City, Arsenal and Manchester United are the three teams that will give their best performances to survive in this competition. Newcastle also cannot be underestimated, Newcastle's performance last season was very good, they managed to outperform other teams such as Liverpool and Tottenham to secure a ticket to the Champions League.
Barcelona appeared in the UCL this season as the La Liga champions, they must perform optimally in order to maintain the chances of achieving their goal of winning the Champions League this season.
The only thing that should please the fans of Barcelona is that they are in the first pot and, firstly, they will receive a couple of weak opponents (with a high probability) and, secondly, they will not play in the group stage with Bayern

Otherwise, nothing has changed and not only English clubs will be a great danger to Barcelona - in fact even average teams will have a chance to knock it out.
