Luciano Spalletti said he will make no excuses for Inter Milan, following their 1-0 home loss to Parma.
Inter have only claimed four points from four games and sit in the bottom half of the table.
Spalletti admits his men have not been good enough, and calls for a change as Tottenham looms closer in the UCL.
“It’s a painful defeat,” Spalletti told reporters. “When you find yourself with four points from four games in front of this crowd and considering the fixture list, it becomes difficult to find excuses.
“We did well for long spells, we were always in their half but we certainly need to offer more than what we did. The responsibility is mine above all if a lot of players are showing less than their full potential.
“I don’t see this as a soft team. The guys are working in the right way with the attitude that you need. At times, perhaps we’re creating more confusion by trying to change the things that aren’t coming off.
“Up to their goal, we were in it but we wasted too many easy chances considering the quality that we have. We need to stay solid, keep our heads and learn also how to make the most of scrappy chances.”
