It is not surprising that even though Inter Milan is the away team, they are still favored in the match because if we compare the two teams, Inter Milan is far superior to Empoli. And in this match I think getting 3 points is a must for Inzaghi's squad because they are far behind Napoli, but in any case in a football match there are always surprises in this case Inter must focus even though their opponent is a weak team, because if they make a mistake of course Empoli will take advantage of it well.
Empoli don't like to lose at home, the last time they lost at home to Napoli 0-1 and before that there were mostly draws and rare wins. Another fact is that Empoli haven't scored at home for 4 games in a row, which is a lot, I think they will try to fix it today, but if their statistics are not very good, then you shouldn't count on their attack, most likely they will focus on their defense again, sometimes they do it better. For Inter today only a win is needed, because any loss of points will allow Napoli to pull away.
It is very unfortunate that Empoli had to lose with a fairly large score at home, to be honest they played quite well in the first half, they were able to withstand Inter Milan's attacks so that no goals were scored, but the mistakes of the defenders that required the referee to give a red card had an impact on the game pattern, Empoli had to play with 10 men and that was utilized by Inter in the second half by creating 3 goals without reply at once, this made Empoli's 3rd defeat in Serie A.
On the other hand, the 3 points brought home by Inter gradually reduced their gap with Napoli in the standings.
In addition, I highlighted another match between Juventus vs Parma, Motta's squad could not win this match even though as the host they could only share points, this result temporarily placed Juventus in 4th position in the table.
I think this season we will see the hunt for the champion between Inter Milan and Napoli only, because the points gap is quite difficult for Juventus to catch up with.
