It's nice that Pep played every one of his outfield players over these two games.
It's hard to argue with the skill level of today's starting 11. It's never wrong to start Thiago. But Thiago is wasted on the left wing, he does not know how to play there and it is not a good match for his skill set. Pep is enjoying starting a different 11 every single game, but this fetish is causing some weird setups that are getting such good results mainly because of the team's excess talent.
Cesc does not play any position, he just roams around out there. His net worth is right around one goal per game.
