(Reuters) - A much improved Napoli are ready to take on Barcelona on Tuesday in what the Italian club's manager Francesco Calzona described as their "match of the year" as they chase a place in the Champions League quarter-finals.

The 55-year-old coach took the helm of the Italian champions hours before their 1-1 draw with Barca in last month's last-16 first leg and Napoli are now on a six-game unbeaten run in all competitions.
