Bayern Munich Save to 100 percent in the Champions League could face a tough test against a dangerous team on Tuesday Napoli in a match that will mark the return of all types for the German team manager.
Jupp Heynckes was in his first stint as coach of Bayern in 1989 when Bayern were eliminated by Diego Maradona in Naples in the UEFA Cup semi-final - and the sides have not met since.
"Napoli is so dangerous team today as they were then," said Heynckes. "They run a lot and play exciting football, which is not Italian."
Bayern lead Group A with six points from two matches. Napoli - who is also undefeated - after four City, Manchester and Villarreal has a zero.
The city has the group's other match Villarreal on Tuesday.
Bayern rejected both Villarreal and the city of dozens of 2-0 in the opening group matches, while Napoli drew 1-1 in the City, then scored his first home game in the competition since the Maradona era by beating Villarreal 2-0.
Naples was also beaten both AC Milan and Inter Milan in Serie A, although Walter Mazzarri side fell to a 2-1 defeat at home against Parma on Saturday.
Napoli president Aurelio De Laurentiis suggested that his players were thinking before the game for Bayern, which is expected to attract a betrayal rarely with more than 60,000 fans at the Stadio San Paolo in ruins.
"We must keep our feet on the ground, (Bayern) is a great team, but everything is possible," said De Laurentiis.
Napoli will rely on his "Three Tenors" for the attack: Marek Hamsik, Ezequiel Lavezzi and Edinson Cavani, whose hat trick against Milan last month was the fifth set of three goals in two seasons.
Napoli is highly dependent on attacks against trying to sprint to their rivals, which could be a dangerous tactic against Bayern.
"We play the kind of football, you do not see every day," said Heynckes after the escape from 4-0 Saturday from Hertha Berlin, Bayern's 12th consecutive clean sheet in all competitions.
"We are making a good impression," agrees Bayern chairman Karl-Heinz Rummenigge, who called in Naples, "the best team in Italy at this time."
Rummenigge has warned against complacency after Bayern opened a five point gap at the top of the Bundesliga.
"We can not start thinking about the season will take care of themselves from now on. We must keep our focus and continue, as we have done so far," said Rummenigge .
Heynckes could afford to take extreme Thomas Mueller, defender Philipp Lahm and striker Mario Gomez, Saturday morning to be ready to go on Tuesday.
However, the Netherlands Arjen Robben is out after a season plagued by back problems and groin.
When the final held next year in Monaco, Bayern wants to move the Champions League.
"We are still very hungry. We are on the hunt for trophies," said the Bayern captain Lahm.
Naples Goran Pandev put the book in the Bayern goal that eliminated the last March 16, when it is still on, even if the thigh strain is likely to rule him this time.
At the same time, the city is trying to boost its European campaign after beating Aston Villa 4-1 on Saturday to go top of the Premier League.
Manager Roberto Mancini is likely to remember Argentina striker Sergio Aguero - Maradona's son-in-law - who only recently returned to training after a groin problem.
The summer signing from Atletico Madrid is expected to start with Edin Dzeko and Mario Balotelli, who has impressed recently with goals in their last two league games.
Playmakers Samir Nasri and David Silva should also be recalled, but Carlos Tevez is still out in the cold, while the club investigate his alleged breach of contract, for allegedly refusing to leave the bench in the loss of the city in Bayern.
"We had a slow start in the Champions League, but hopefully we can pick up and put in a performance that we know we can," said midfielder James Milner in the city.
Villarreal won only two of their last 15 games in all competitions, and drew 0-0 at Getafe on Saturday.
"It 'sa difficult group, and, of course, we need a taste of Champions League football together, but we know that we can improve our resolutions Champions League so far," said Millner. "Win is of paramount importance and I am sure that we understand.
