Leonardo Bonucci  has voiced his disappointment with Juventus ' results in recent weeks and has urged his team-mates to show humility once more in order to get back on track.The reigning Serie A champions were beaten 2-1 by Sampdoria last week and had to settle for a 1-1 draw versus Parma on Sunday afternoon, allowing Lazio to close the gap in the Italian top tier table to three points."We have to concentrate more and rediscover our edge because Lazio and Napoli are on our heels," Bonucci was quoted as saying on the club's official website. "We still have an advantage, but we require hunger and humility to increase the gap again."Against Sampdoria we had the wrong approach in the second half and it was an important lesson for us."Versus Parma, on the other hand, we were more careful. That’s football, though: there are times when you don’t get the results and don’t come away with the points."Juventus will be looking to return to winning ways next weekend at home against Udinese, who came from behind to beat Fiorentina this weekend and sit eighth in Serie A.
