The coach watched as his side gave up the lead to draw yet again and admits the Nerazzurri must find a way to improve their low confidence
Luciano Spalletti questioned the character of Inter's players after they were held to a fifth successive draw in Serie A.
The Nerazzurri are now eight games without a league win following Saturday's 1-1 result against a Crotone team managed by Inter legend Walter Zenga.
Eder headed the home side in front after 23 minutes at San Siro but Crotone hit back after the break, Andrea Barberis capitalising on a lucky break to poke home an equaliser.
