Gian Piero Gasperini insists he “definitely saw an improvement” in Inter and explained his substitutions.
“I definitely saw an improvement, especially with the chances we created. Roma are very difficult to face, but we allowed them few scoring opportunities thanks to a performance of concentration and grit,” he said of the 0-0 draw.
“It's a shame we were unable to make the most of the chances and the spaces they left, above all towards the end.
“Yuto Nagatomo had some important moves and there were some big spaces to run into. We perhaps should've had a better final ball in and that would've given us a goal.”
The Nerazzurri switched to a 3-5-2 system, but the San Siro crowd jeered when Sulley Muntari replaced Diego Forlan.
“Our strikers had to come back on Daniele De Rossi to pressure him. I made that change because at that moment we needed a midfielder.
“Wes Sneijder had done very well, but was certainly tired and struggled to maintain his position, as did Forlan, so I needed someone to help break up Roma's possession.
“It's no coincidence that after that substitution we created our best scoring opportunities.”
Inter were beaten 4-3 at Palermo last week, but now failed to hit the back of the net against both Trabzonspor and Roma.
“The goals aren't coming, we just have to accept it's one of those moments and later on we'll end up scoring much easier chances than we've had so far.
“We only played a couple of days ago and at the moment are using the same players a lot. With time our fitness will improve and so will the performances.”
