The results from Lazio is not surprising. I expected them to win Spezia comfortably. Lazio is that good. They will not lose that second spot position to anyone. It will be good to see them in the champions league because they deserve it. If Napoli had not been in such a brilliant form, we might have been seeing Lazio at the top of the table now.
Lazio are making one of biggest surprise in Serie A, just after a great success of Napoli. Lazio did not spend too much money for their squad which in fact does not have too many changes in recent seasons. It is more surprise to see their attacking system works very well in this season after missing their best striker Ciro Immobile in many matches by his injuries.
Lazio's victory over Spezia 0 - 3 further strengthened this club's position as runner up. It's still difficult for Lazio to get closer to Napoli, but at least they are a bit safe from the pursuit of the clubs who are in 3rd position and so on. Indeed, Lazio's performance in the last few weeks has improved very well, not only in their performance against small clubs, but also big clubs, they can optimize various conditions to continue to win.
With this winning, Lazio secure their second position and have a safer condition in top four competition among some big clubs. They will wait for results of AS Roma, AC Milan and Inter Milan to see will they expand gaps against those clubs after this week. Spezia simply are not strong enough to challenge and get points from Lazio.
