The 2017/18 UEFA Champions League season is already under way, a 334-day journey that ends in Kyiv next May.

Get the lowdown on the who, what, where and when.

When does it start?

It already has! The new season kicked off on 27 June – just 21 days after Real Madrid were crowned champions in Cardiff – with the first of four qualifying rounds, culminating in the play-offs at the end of August. The group stage begins on 12 September and runs every two or three weeks until 6 December. After a two-month winter break, the knockout stages start on 13 February.

How does qualifying work?

Twenty-two of the 32 teams that will contest this season’s title are confirmed, and they will be joined by ten play-off winners at the end of August. There are two qualifying paths:

Champions Route – as the name suggests, this path is for domestic title holders, starting with the ten lowest-ranked nations in the first qualifying round. The five victors are joined by the next 29 lowest-ranked champions for the second stage, with the next three sides added for the third qualifying round. The ten winners then face off in five play-off ties. All ties are played over two legs, home and away.

League Route – this path features sides from high-ranking countries who finished anywhere between second and fourth in their domestic leagues. There are two stages, with ten teams starting out in the third qualifying round and five sides awaiting the victors for the play-offs. All ties are played over two legs, home and away.

Depending on who the qualifiers are, Tottenham could be in Pot 2 or 3, while Roma, Beşiktaş, Feyenoord and RB Leipzig will be in Pot 3 or 4.
