Diego Milito feels Inter are being treated unfairly by referees in the wake of the Nerazzurri's 1-0 Serie A loss to Lazio on Monday.
Head coach Walter Mazzarri previously voiced his frustration with the performance of officials in Monday's encounter shortly after the final whistle and Milito has now moved to question the agenda of those in charge.
"How are we to interpret the refereeing decisions that are going against us? It's really hard. We keep saying the same things," Milito told Inter Channel.
"They haven't given us a penalty yet and I don't think that's normal.
"There was that foul on Rolando, [Fredy] Guarin's burst forward that might have changed the game – episodes like that are penalising us at the moment."
Milito returned to match action against Lazio after a lengthy spell on the sidelines and he was pleased to be back.
"I couldn’t wait to get back on the pitch after so many months out - it felt great."
The 34-year-old has made just four Serie A appearances so far this term due to physical problems, scoring twice in the process, having missed the second half of last season with an Achillees injury.
