#4 Favourable draw & possible January reinforcements

Although the squad has quality, the lack of experience in the Champions League is a drawback. This implies that the draw is a huge factor and luckily, Liverpool avoided a few tough groups including the one with Real Madrid and Borussia Dortmund to get a good draw.
Sevilla are not the same team that beat Liverpool in the 2016 Europa League final. Spartak Moscow and Maribor could prove to be potential banana skins but Klopp's team is expected to deal with them relatively well. In fact, Liverpool are favourites to top the group.

Thus, getting through to the knockouts will bring Liverpool to January where the club can rectify problem areas. Virgil van Dijk continues to be the top defensive target and the Merseyside club will benefit massively from the move if it happens in January.
Further, Naby Keita's move next summer could be preponed if Leipzig do not make it to the knockout stage. Also, Divock Origi's loan move to Wolfsburg has a recall option in January. This can prove to be useful in case any of their current strikers pick up injuries and if Origi makes use of the playing time in Germany to finally realize his potential.
Thus, Liverpool can get stronger for the knockouts and can give any of the favourites a run for their money. This in itself is a strong reason why the Champions League trophy will be paraded around Merseyside in 2018.
