Chelsea legend Gianfranco Zola can't split them and Champions League opponents Napoli.
The 45-year-old enjoyed spells at the two clubs during a glorious playing career and he remains loyal to both outfits.
"I'm split into two," the former Italian international told La Repubblica.
"If I said I favoured one team over another then I would feel like a creep.
"I just hope that the best team wins.
"Both sides have great sets of fans and I remember them with gratitude."
