Lazio is not a weak team, they played quite well and were consistent last season. Lazio also has a chance to win in the match against Inter.
but Inter themselves are now in much better form. Lazio must be wary of Martinez and Lukaku. and more importantly a very strong Inter midfield so far.
Although lazio is not a weak team, but Lazio is not a difficult opponent for Inter, I'm sure of that. The last meeting of the two happen a few months ago, and at that time Inter managed to win 2-1. Changes only happen on the front lines, where at that time Inter were still reinforced by Alexis Sanchez as the main striker, and now Inter have Romelu Lukaku. The combination of two stars Lukaku and Martinez is one to watch out for in Serie A this season.
