(Reuters) - While Inter Milan are romping towards a seemingly inevitable Serie A title, the battle for Champions League qualification is heating up with Napoli's top-four ambitions set to be tested when they visit the league leaders on Sunday.

Runaway leaders Inter have a 16-point advantage over second-placed AC Milan with 10 rounds remaining, while champions Napoli are seventh, seven points off fourth-placed Bologna in an increasingly tight contest to book a spot among Europe's elite next season.
