The one who was Bella
Aimar is a nonfacor so far, you guys are loosing the midfield battle in a pretty onesided way to Porto's trio.
Your problem is Porto is killing you on the wings forcing Nolito and Gaitan to drop deep to help out, but when you win the ball you have almost no-one to hold it a bit or move forward with - and Porto are all over you once they loose the ball.
You also have no throughball target with Cardozo so it pretty much makes you predictable/uneffective.
Luisao is playing fantastic so far for you though.
Don't waste your time on jealously; sometimes you're ahead, sometimes you're behind.
The race is long, and in the end - it's only with yourself.
