Think was one of the first games in a while that the starting 11 played like a final and were extremely motivated. We had this kind of intensity last year when we were fighting for LaLiga, but didn't match it with the level of attacking football. Perhaps a quality issue given what the Joao's have (short term) added to our left side.
As such, guys like Raphi and Joao looked the business. Hell even, Lewy was closing down and working harder off the ball but like Raphinha lacked the finish.
I reckon words were said about Barca which Felix brought to the players attention, which coupled with Xavi approach lit a fire under the players ass. It did seem a bit personal for more than just Felix.
If we can put that sort of effort in the majority of games (let's face it, it is expected to have dud performances here and there) then guys like Raphinha who are hardworking but not individually spectacular will perform way better purely by being surrounded with movement and speed.
