Now the Champions League format allows the teams to better prepare for the games in their respective championships.
Inzaghi did not keep Martinez in his squad because Martinez is not in good form. In the first three matches we did not see a better performance from Martinez. This is why we haven't seen Martinez in Inter Milan's starting XI. If Martinez is in good form, we would certainly see Martinez in Inter Milan's squad. Because Inzaghi will certainly give more importance to the Champions League match than the Serie A match. It would have been even more creditable to Inzaghi if Inter Milan had somehow managed to win against Manchester City.
I don't think Manchester City made any tactical mistakes in this match. Manchester City players played well enough we have to admit that. But the opponent Inter Milan also played very well. This is why Manchester City is not able to win.
City's first serious attack was in the 69th minute, and before that there were no dangerous chances. At the end of the half, City still could have scored, but Sommer played well and Inter managed to get a draw in this match.
