Well it also coincided with Lukaku getting back in form. We had a true rotation because our back up team included Brozovic and Lukaku. The form of those two was helping carry us in the league while we were playing our preferred 11 in CL and Coppa Italia.
Also, again, when Lukaku wasn't playing or when he was still getting in form, getting just 15 minutes here and there, Inter was actually mostly winning games.
So when he finally came back and played, it was 64 minutes in a win against Napoli, 35' in a draw against Monza, had knee infflammation in our win against Verona, came back to play in loss against Empoli (14'), win against Cremonese (14'), win against Milan (20'), draw against Sampdoria (66'), win against Udinese (66', also his first goal after a long time), Bologna loss (63'), Lecce win (19'), Spezia loss (90', a goal for him), Juventus loss (79'), Fiorentina loss (90'), Salernitana draw (85', 1 assist), Monza loss (90')
and then finally the last run of 8 games with 7 wins, 1 loss, played most minutes, didn't play against Verona (our 0:6 win) and in this run of 7 games he played his numbers are really good.
Also, Lukaku played a lot of minutes in our Bologna loss, our Sampdoria draw, Spezia loss, Juventus loss, Fiorentina loss, Salernitana draw, Monza loss - where he contributed only 1 goal and 1 assist. This is why people were mad last season. (He also scored in win against Udinese)
He also barely played in our Cremonese win, in our Ac Milan win, in our Lecce win.
So now answer me this. If Lautaro gets injured, comes back to the fray and then takes 15 games to get back into competitive form, how many FIF members would lose their shit?
Nobody can take away from Lukaku that he was actually good in his last 7 Serie A games for us. But it's not like he came directly back from an injury and started bossing. It's too little, too late. Lukaku already started in the 4th of January game against Napoli and then he had to miss only 1 game because of injury. So from 4th of January to 23rd of April, when we played Empoli and Lukaku scored a brace, Lukaku played in 14 Serie A games!!!!!!
