SSC Napoli's struggles against Beşiktaş JK have complicated their advance towards the qualifiying positions in Group B and they will be looking for a maximum return at home to FC Dynamo Kyiv.
• Napoli will qualify with victory as long as SL Benfica also win away to Beşiktaş. Dynamo have to win to remain in contention for the top two places but only if Beşiktaş do not win. Anything less than victory and Dynamo will be certain of finishing fourth.
• On matchday one, their first ever competitive encounter, Arkadiusz Milik scored two first-half headers as last season's Serie A runners-up came from behind to win 2-1 in Ukraine. Denys Garmash had put the hosts ahead; Serhiy Sydorchuk was later sent off for two bookings.
• The home game with Benfica on matchday two produced a superb attacking display by Maurizio Sarri's side, who led 4-0 by the 54th minute with Dries Mertens scoring twice at Stadio San Paolo. The visitors cut the deficit with two late goals.
• Qualification could have been sealed on matchday three – the earliest in UEFA Champions League history – but Beşiktaş ran out 3-2 winners in Naples and then threatened a repeat in the return only for Marek Hamšík's stunning equaliser to make it 1-1.
• That home defeat was the Partenopei's first in 19 European home games (W13 D5) since a 3-0 loss to FC Viktoria Plzeň in the 2012/13 UEFA Europa League round of 32.
• In 2013/14, Napoli's most recent UEFA Champions League group stage campaign, they won all three home matches – against Borussia Dortmund, Olympique de Marseille and Arsenal FC. Yet they failed to qualify for the knockout rounds despite collecting 12 points, more than any other side that has missed the qualification cut.
• On matchday two, 18-year-old Viktor Tsygankov scored his first UEFA Champions League goal just three minutes into his second competition appearance to earn a 1-1 draw at Beşiktaş, Dynamo's sole point so far.
• Before last season the Kyiv club had won only four of their 31 previous group stage fixtures. An improved campaign helped them add another three wins to that total as they reached the last 16 for the first time since 1999/2000.
• Their current record stands at seven wins in 41 group stage fixtures.
• Last season they won at Maccabi Tel-Aviv FC and FC Porto in Group G. They went out to Manchester City FC in the round of 16, losing 3-1 at home and by the same aggregate score after a goalless second leg. It was the first time they had reached that stage since 1999/2000.
• They have won just twice in 21 encounters with Italian clubs (D6 L13), both victories coming against AS Roma in the 2004/05 UEFA Champions League group stage. The game in Rome was a 3-0 forfeit success as the match was abandoned after referee Anders Frisk was hit by an object thrown from the crowd. Dynamo won the return 2-0 in Ukraine.
