Lazio faced both in the opening two rounds of the season, losing first in Rome and then in Turin.
“Having faced them I think they will play the same role as last season," Inzaghi admitted on Rai Radio.
“They are two great teams coached by two excellent Coaches in [Max] Allegri and [Carlo] Ancelotti.
“The condition is improving though and we have our first win, so now we'll take advantage of this international break to work and prepare well. Empoli won't be a simple match.
“We had a very good game against Frosinone and I congratulated my lads. These are games you have to win, but they aren't easy.
“We know how hard these matches are and we were coming off two losses, which is another negative factor."
