I think Arsenal may still yet exit this tournament. Their next game is in Greece, and it will be very tough. A draw puts Olympiacos through, which would most probably mean that Arsenal will go to EL, which I don't think they will deign to take seriously, if the prevailing attitude in the Prem is anything to go by.
As for Tottenham and Lpool--I hope they draw Napoli and Fiorentina. I think Napoli can take either of em, and I would fancy Fiorentina (if they make it) doing the same. I think Fiorentina will win in Switzerland tomorrow.
I think Chelsea and Man U should make it to the next round as should Man City. But I don't see Chelsea doing anything special, which leaves the two Manchester sides. I just hope Juve top the group, and City draw Barcelona or Real/PSG, or Bayern Munich.
Anyway, the point is, anything can happen obviously. I am optimistic because I see a very competitive Serie A this year, and it will show. For example, if Roma make it to the next round, they will invest in their defence in January.
Juventus do well when given space, and they get that in Europe. Napoli are sizzling, and Sarri is a conscientious manager as is Sousa. Both want to win the EL and both will take it seriously.
Let's see...Forza Italia!
