I was there when we played against this past summer. They were further along in their preperation considering their league was starting 2 weeks later whereas Serie A still had a month. We played a weak team that looked like this:
Inter (4-2-3-1): Belec; Santon, Cordoba, Obi (Milito h-t), Chivu (Mancini 58); Cambiasso (Krhin 79), Zanetti; Vieira, Motta (Ibrahimovic 58), Burdisso; Balotelli (Quaresma 79).
While they fielded this team:
Chelsea (4-1-2-1-2): Cech (Turnbull 62); Ivanovic (Mancienne 62), Carvalho (Alex h-t), Terry (c), A Cole (Hutchinson 78); Mikel; Malouda (Deco h-t), Essien (Belletti 62); Lampard (Di Santo 87); Drogba (Anelka h-t), Kalou (Sturridge h-t).
We lost due to a goal JC would have stopped in his sleep and a BS penalty. That's it. We could potentially give them a run for their money IF we play with balls and technique.
