Inter Milan boss Walter Mazzarri has warned of a banana skin for their Europa League qualifier with Iceland's Stjarnan. Inter face a qualifier against the Icelanders next week.
"Football has levelled out now, so you cannot underestimate any opponent," warned Mazzarri.
"If we look at history, we realise the surprises are always right round the corner. We must prepare well to reach the two legs against Stjarnan in the best shape possible.
"We risk running into some ugly surprises if we even slightly underestimate the obstacle in front of us. Don't forget Iceland nearly qualified for the World Cup."
