[4] Having proved himself at domestic level, Napa set his sights at another shot for the European belt against reigning champion Carmelo Ballone.
"[5] Napa was as good as his word winning in October 2008, a majority decision verdict over the Belgian after coming on strong in the latter part of the fight and putting Ballone down in the 10th round.
[6] Unfortunately for Napa his hold on the title was to prove short lived when in March 2009 he lost a unanimous decision in his first defence against Frenchman Malik Bouziane.
[8] On 22 January 2010, Napa defended the title against Jamie McDonnell only to lose a split decision verdict to the man from Doncaster.
Despite coming on strong in the eighth round and being ahead on all the judges scorecards Napa claimed that the heat in the hall had affected him and that he'd struggled to make the bantamweight limit.
