Claudio Ranieri is hoping Roma's decision not to bring in reinforcements in the winter transfer market does not prove costly in the title race.
Roma, who are also in contention for the Coppa Italia and the Champions League, are in the process of being sold and, unlike, AC Milan, Inter and Juventus, did not strengthen their squad in January.
Ranieri said: "(Roma sporting director Daniele) Prade said that Milan and Inter were in need of reinforcements, but we didn't?"
"I am not in agreement with him. They were already stronger than us and have had more money to invest, hence, they have intervened in the market.
"We, at this time, could not invest a penny. I hope that this market does not penalise us."
Ranieri will not have to wait long to find out as his team travel to the San Siro on Sunday evening to face Inter.
