That first 30 minutes was truly amazing. A throwback to 2011, some amazing Tiki Taka and Busi, Iniesta and Neymar showing their skills. I've been frustrated watching Barcelona play this season, playing down the wings and not changing the angle enough. Look at how many times Messi, Alves, Busi and Iniesta changed the angle with quick 5 yard passes, pure Futsal, and it was so effective, Sevilla were chasing shadows in the first 30 minutes.
