Perhaps it will be easier for Barcelona to do well in the Europa League than in the Champions League. However, winning the Europa League title will not be easy for Barcelona. Because there are strong teams like Arsenal and Manchester United. Barcelona's squad is not weak. Then competing with these teams to win the title is very difficult. I think this season's Europa League will be very competitive, just like the Champions League.
Well, the European League is now quite visible, many giant clubs have started to make the Europa League a place to improve their performance. Although not very prestigious, the more big clubs enter the European League, the competition is as exciting as the Champions League. After all Barcelona, Arsenal, and Manchester United are quite serious about doing their best in the Europa League.
