Apart from the Champions League, there are two other European football competitions: The Europa League and the newly formed Conference League, created by the UEFA. Because of the new format, there are some changes to the competition, and now, unlike last season, the teams who finish third in the Europa League are not disqualified, but they play against Conference League teams. But first things first, who made it through the last 16 in the Europa League?Who, when, how: Champions League knockout stage explainedThere are 24 clubs who are through to the last 16. But, if you know your math, something is wrong here. Yes, there are 8 clubs more than needed, but that’s the new format. Eight clubs who finished first in their Europa League groups are free of the next play-off draw and will rest until March, when other teams finish their games. So, second placed teams in the Europa League and third placed teams in the Champions League are playing first, and the draw is on Monday, 13th December at 15h, Nairobi time.Seeded teamsBetis (ESP)Braga (POR)Dinamo Zagreb (CRO)Lazio (ITA)Napoli (ITA)Olympiacos (GRE)Rangers (SCO)Real Sociedad (ESP)Unseeded teamsAtalanta (ITA)Barcelona (ESP)Dortmund (GER)Leipzig (GER)Porto (POR)Sevilla (ESP)Sheriff (MDA)Zenit (RUS) After they finish their games, the winners will draw with Europa League group winners, who will still be seeded than. The same rule that in this round, teams from the same country cannot play against each other applies.More bad news coming from Spurs’ headquartersAnd then there is the Conference League. Luckily, the same rules for the Europa League applies: Winners of the group stage are trough the last 16, and will wait the winners of the playoff games between second placed clubs in the Conference League and third placed clubs in the Europa League. And this year, there are a lot of good clubs who failed to qualify for the last 16 of the Europa League and will have to settle for the third competition.“I’ve got to be honest, I don’t even know what the competition is. In all fairness, I was focused on the Europa League and winning this group, or at the very least finishing second, so with all due respect to the competition, I’m not sure what it is. But I’m sure I will find out soon enough” said Leicester coach Brendan Rodgers, after his team miraculously failed to reach the last 16 and will have to play in the Conference league now. And they are not alone, as clubs such as Celtic, Marseille, Ferenbache and PSV will move to the third ranked UEFA competition.SeededBodø/Glimt (NOR)Maccabi Tel-Aviv (ISR)PAOK (GRE)Partizan (SRB)Qarabag (AZE)Randers (DEN)Slavia Praha (CZE)One more team to be confirmed – Spurs-Rennes game has been postponed due to CovidUnseededCeltic (SCO)Fenerbahce (TUR)Leicester City (ENG)Marseille (FRA)Midtjylland (DEN)PSV Eindhoven (NED)Rapid Wien (AUT)Sparta Praha (CZE)
