I agree on his workrate being shit, but if Valverde is serious about 4-2-3-1 Özil could be good at Barca, if we maintain a posession based style.
Özil is his best when having the ball. Roberto is a Duracell-bunny and with either Sergio or Paulinho behind him, he could be able to prove capable. No way near the same agility, stamina or quality atm as other WC options, but who is the alternative for our midfield?
Coutinho is a no-brainer, but seems impossible to get. I would hope for Lemar due to his link-up with mate Dembouz in the french NT, but he is more of a winger than natural CAM as well (although he was excellent tonight).
I would take Özil over Di Malaria any day of the week tbh, but I agree it is not the signing we hoped for.
