The Champions League is back underway with a new format - but what do the teams need to qualify for the knockout rounds of the competition?
A new format brings new expectations in Europe this season, with clubs looking at the mathematics to see how many points they would need to qualify for the knockout rounds in the new league phase structure.
Instead of the traditional eight groups of four - with the top two from each group qualifying for the last 16 - a new 'Swiss-style' 36-league format has been introduced this season.
The top eight sides in the league will qualify automatically for the last 16, while the teams finishing in ninth to 24th place will compete in a two-legged play-off against each other to join the top eight teams in that round of the competition.
The bottom 12 teams - from 25th to 36th - will be eliminated with no access to the Europa League.
So to avoid an early elimination - how many points do you need? And what about the number needed to skip the play-off round and finish in the top eight?
The Opta supercomputer believes 16 points from a possible 24 - so five wins and a draw from eight matches, or other combinations - would almost certainly be enough to finish in the top eight, which guarantees you a last 16 spot in the New Year.
The data also believes 15 points - so five wins from eight games, or other combinations - could be enough to sneak into eighth place, with that points tally being enough in 73 per cent of Opta's 50,000 simulations of the league phase.
Fourteen points, so four wins and two draws, is unlikely to be enough for a top eight finish - so the race to five wins is likely to be the target for the biggest sides.
To finish in the top 24, which guarantees you a play-off spot at least, Opta believes 10 points - so three wins and a draw, or other combinations - will almost certainly guarantee you a place in that round.
It means whichever teams win in the opening round of Champions League fixtures need just seven points from the remaining seven games to guarantee themselves a play-off spot.
Nine points - so three wins from eight games, or other combinations - could be enough to finish 24th, with that points tally being enough in 69 per cent of the simulations.
But just eight points - so two wins and two draws, or other combinations - runs the risk of elimination, with that points tally being sufficient in just 16 per cent of the simulations.
So teams will be targeting at least three wins from eight to give them the best possible chance of reaching the Champions League knockout rounds.
