Chievo coach Domenico Di Carlo has warned his side not to become over-confident ahead of their trip to Rome to face strugglers Lazio tomorrow. The Flying Donkeys produced a fantastic performance to beat Juventus 1-0 last weekend. Having lost their previous three games, the men from Verona clinched three vital points courtesy of a goal from Pablo Granoche, lifting them 10 points clear of the drop zone after 20 games played. "We produced our best against a strong side,'' Di Carlo said. "Before the Juventus game we had hoped to do well but we didn't expect to surprise the Turin outfit. "However, now it is important that we don't make the mistake of lifting our heads too high. "We have to keep our feet firmly on the ground. "The victory against Juve is important for the standings and I'm sure it will give my players a big boost in confidence. "But we must remember that we lost our previous three games and hence, we cannot get carried away.
