its moved out from around 1.4 in the last few days, probably because of all the lazio injuries. due to their financial crisis of the last few years, they had a thin enough squad going into this competition. cana, diakate, brochhi, dias, maybe hernanes too are all out afaik, plus they sold cisse and didnt manage to finalise a replacement before the deadline, so they're very reliant on klose up top.
however, they are still in very good form and cesena are poor on the road. maybe have a look at the AH for cesena. you'd get similar
odds (1.5) for cesena +1.5, lazio havent been the biggest scorers at home 14 in 11, cesena have conceded 11 in 21.
arrigoni played a really cautious 3-5-2 to frustrate napoli the last time out, so you might expect to see that again. but i just dont see him smelling blood here with the lazio injuries and sending out a team to win.
